Description of the invention (1) A7 B7 In the Ministry of Destruction, the young and middle-aged soldier J disappeared in a cooperative private seal to cross the related applications. The present invention is based on application 60 / 049,341. The application date is June 11, 1997. {Said, 60 / 059,463, application dated September 22, 1997, and 60 / 081,917, application dated April 16, 1998 "Field of the Invention The present invention relates generally to soil testing technology. BACKGROUND OF THE INVENTION It is often important to determine the resistance of soil moth to liquefaction, the degradation characteristics of soil moth, the shear modulus of soil when it is worse than low shear deformation, and the change in shear modulus of soil with shear deformation. These soil properties and others are often needed to analyze the response of a location or infrastructure system to dynamic loads caused by earthquakes, waves, or mechanical vibrations. Soil properties can be determined by field experiments. For example, the soil liquefaction resistance can be determined by a penetration test. The test includes penetrating the closed-end probe into the ground at a slow controlled rate or driving the barrel into the ground with a violent impact. The liquefaction resistance of the soil has an interactive relationship with the resistance of the probe or cylinder when it penetrates. The technique of measuring the liquefaction resistance by torsion-induced soil damage is disclosed in Robert & Wanda Henke patents Nos. 4,594,899 and Nos. 5,203,824. The test device exemplified in this patent includes a pair of concentric open cylinders inserted into the soil to be tested. The torsional force applied to the inner cylinder and the response of the cylinder to the soil to the applied torque can be measured by a sensor installed in the inner cylinder. In this kind of soil damage test, a sample of soil is taken from a bored hole, and the test device lowers the bored hole to test the soil. The test device is screwed into the borehole. The test device is subjected to a general force or torsion or it comes from soil.Please read the note on the back side first.

The response of the instrument head 16 and the cylinder 14 is a rotation oscillation time t 'at an angle of 0, and the method is obviously strongly related to the shear modulus and related deformation parameters of the test soil as shown in Figure 1B, as shown in Figure 1B. Show. The shear modulus and related parameters were obtained from the torque and rotation measurements by means of simulation tests through analytical methods. Rigid soil response 17 is shown in Figure 1B compared to soft soil response 15. Referring to FIG. 2, the probe 10 of the single-cylinder torsion cylindrical shear test system 18 is clamped to the drill assembly 12, and then the drill body 14 is penetrated into the soil to be tested. The probe includes a probe 10 penetrating the inside of the drill assembly 12 penetrating the cylinder 20, the axial load unit 22, and the lateral clamp 24. The final sample of the Ministry of Justice is printed by a ^ Jr. Consumption Report ii --------- I- (please read the note on the back < 1 ^ item4 and write this page) as As shown in FIG. 3, the lower portion 10a of the probe 10 includes a housing 28, a head 30 equipped with an instrument, a probe barrel 42 and a portion separated from each other at B. The joint 32 between the housing and the equipped instrument head / probe barrel assembly allows axial misalignment between the two units', but when the two units are fully engaged, they can oppose relative rotation by friction. The barrel extractor lever 34 is connected between the probe housing 28 and the instrument head 30. The collar 36 of the magnifying head 37 engages the barrel extractor rod 34 with the probe housing 28; and the seat 38 of the magnifying foot 40 of the barrel extractor rod 34 can provide the barrel extractor rod 34 and equipment Engagement between instrument heads 30. The V-shaped groove 32b is formed in the general body 28 to match the V-shaped ring 32a provided with the instrument head 30. The groove 32b and the ring 32a can assist in matching the two parts. The size of this paper is applicable to Chinese National Standard ((, NS) Λ4 specifications (210X297 mm) 6 The Ministry of Standards and Standards Bureau of the People's Republic of China has eliminated the seal of the cooperative cooperative A7 B7 V. Description of the invention (4) Originally as shown in Figure 3 As shown in the figure, the probe head cylinder 40 equipped with the instrument head 30 is suspended above the soil A by the barrel puller rod 34. The joint between the housing and the equipped instrument head k32 is separated from the probe cylinder assembly by the maximum distance. The barrel extractor rod assembly is limited and the collar 36 and seat 38 hold the head 37 and feet 40. The head and feet of the barrel extractor rod 34 and the corresponding opposite surface structure make the housing and the instrument head 30 / The separation distance between the probe barrel 42 assembly is not greater than the original distance when the head 37 of the barrel extractor rod is holding the collar 36 and the foot 40 of the barrel extractor rod 34 is holding the seat 38. Tube The taper of the foot 40 and head 37 of the body extractor rod and the corresponding bearing surfaces 38, 38 facilitate proper alignment between the housing and the instrument head / probe barrel assembly. The foot 40 can be connected to the rod 34 by a bolt 41 An accelerometer 33 can also be provided. As shown in Figure 4, the probe barrel 42 penetrates the soil A to be tested by the penetration barrel in the indicated direction. The required reaction force of the cylinder comes from the drill assembly (Fig. 2) to which the probe is clamped. The probe is in the fourth compressed state, and the housing 28 and the instrument head 30 / probe cylinder 42 assembly are connected to each other. Contact at the joint 32. During penetration, if the compression force used in the probe is transmitted through the penetrating cylinder to the instrument head 30 / probe cylinder 42 assembly through the housing. The compression force is not transmitted through the torque load unit 44 This point is why it is necessary, because the compression force that occurs during penetration is likely to be quite large. Although the housing wall may be strong enough to tolerate this force, the torque load unit 44 is usually a wall It is thin and can only measure low torque. The load unit may collapse under moderate compression. When the probe is compressed, the barrel extractor rod 34 is freely suspended by the barrel extractor rod collar 36. The barrel is pulled out The distance between the foot 40 of the instrument and the seat 38 of the foot is the maximum distance. The paper size is Chuzhou China National Standard Net (CNS) Λ4 specification (2) 0X297 mm. I n I Thread (please read the note on the back first) Please fill in this page for matters) A7 __ B7 •--V. Description of Invention (5) As shown in Figure 5, in the next stage, the probe barrel 42 completely penetrated the soil, and the penetrating force was released and the probe was ready for testing. The probe is in a partially hidden fe, of which the housing 28 is equipped with an instrument head 30 / The probe cylinder 42 assembly is lifted (eg, using a penetrating cylinder) with a medium amount; in other words, there is a gap B of a predetermined size at the junction 32 between the housing and the instrument head 30 / probe cylinder 42 assembly. In this case, during the test, all the torque applied to the instrument head 30 / probe cylinder 42 assembly passed through the torque load unit 44 but not the case «28. The load unit 44 was fixed to the instrument head 30 by screws. If some of the applied torque passes through the assembly to the instrument head 30 / probe barrel 42 assembly, this torque is not measured, and the torque measured by the torque load unit does not represent the torque applied to the instrument head 30 / probe barrel 42 The complete torque of the assembly. This results in inconsistency in the interpretation of the test results, because the torque excitation cannot be fully defined. In addition, the instrument head 30 / probe barrel 42 assembly is separated from the housing 28, and this assembly can rotate freely during the test. In this case, the test soil is expected to have the greatest impact on the rotation response of the instrument head 30 / probe barrel 42 assembly. This response can reflect the relevant characteristics of the soil to be tested to the greatest extent possible. Conversely, if the instrument head 30 / probe tube 42 assembly is constrained due to the release of the ship 28 and the draught preparation head 30, the test soil will be fit *, and the impact of the rotation reaction will be reduced. the amount. The assembly response cannot reflect the relevant characteristics of the test soil to the same extent as when the total composition of the housing and the instrument head 30 / probe barrel 42 is opened. In this way, the required soil properties cannot be estimated from the test results as in the latter example.

The torque is applied to the assembly equipped with the instrument head 30 / probe barrel 42 through the load unit 44, and then the rotation response of the assembly equipped with the instrument head 30 / probe barrel 42 is detected by the accelerometer 33. As shown in the figure, 'In the next stage, the probe cylinder 42 is pulled out from the test soil by penetrating the cylinder 20 (the second stage).' The probe is in the fully extended state (the third circle) in the first stage. The largest possible amount of the body 28 and the instrument head 30 / probe barrel 42 assembly separated from each other is denoted by C. At this stage, because the soil exerts resistance on the probe barrel 42, the barrel extractor rod 34 is under considerable tension. The tension does not pass through the torque load unit 44. In this way, the torque load unit 44 is protected from damage during the extraction phase (and the penetration of the probe barrel). As in the first stage (3rd circle), the probe is fully extended, the head 37 of the barrel extractor rod 34 is held on the collar 36 of the barrel extractor rod, and the foot 40 of the barrel extractor rod 34 Stomp foot seat 38. The tapered shape of the head 37 and the foot 40 of the barrel extractor rod 34 and the corresponding bearing surface facilitate the proper alignment between the housing 28 and the instrument head 30 / probe barrel 42 assembly. It is also possible that the opening and closing of the joint 32 between the housing 28 and the instrument head 30 / probe barrel 42 assembly can be monitored using a position measurement sensor, electric switch or axial load unit, and its measurement is along the probe's longitudinal axis. The internal force β is a shell. The area surrounding the probe can be pressurized. _ For example, it is valuable when the probe is immersed in water for testing. The internal pressure can reduce some of the large external fluid pressure, such as the adverse effect of large stresses in the thin-walled torsion load unit. As shown in Figure 7 of Level 7, the cylinder 42 has a slit 43 including the upper part 46.

Invention description (7) " ~-The lower part 48 can be replaced, and the lower part has a penetrating series. The lower part was torn to the upper part 46 during the test. An example of an effective attachment method is to press the lower part material into the upper part 46. The alignment tool 51 is used to align the longitudinal slits 43 of the lower member 48 and the slits 43 of the upper member 46 during the press-fitting operation. Relative to each other. In use, if the penetrating edge 50 of the lower member 48 becomes excessively worn or damaged, it is simply pressed out by the upper member 46. The new lower part 48 is then pressed into the upper part to restore the cylinder to its original condition. Since the lower part is much cheaper and easier to replace than the entire barrel, the use of segmented barrels is cost effective. The lower part and the upper part have matching deflectors 49. v A variety of information can be used to indicate liquid pyridoxine resistance from the results of a single cylinder torsion cylinder shear test. For example, liquefaction resistance can be indicated by the maximum shear strain appearing in the test soil during a highly maneuverable test using a torsion cylinder impact shear test with a single end opening test cylinder. In the torsion cylinder impact shear test, as shown in Fig. 1, the test element is a cylinder with a single open end. The barrel is maneuvered by the torque impacting the load. The response is the rotation of the cylinder. The maximum shear strain occurring in the soil subjected to the test can be effectively inferred from the amount measured using this test. "Highly liquefiable soil shows a high maximum shear strain; soil resistant to liquefaction shows a low maximum shear strain, and can be moderately liquefied. The soil shows the maximum intermediate shear strain. For higher maneuvers, it is found that the torsional cylindrical impact shear test can induce maximum strain maximum in saturated loose silt sediments (eg, highly liquefiable) and minimum in clay-like sediments (eg, non-liquefiable). . The maximum value of the shear strain is usually part of the analytical simulation to estimate the shear modulus and related parameters.

Description of the invention (8) Shear strain estimation can also be performed during the test Measured directly. In addition to replacing the maximum shear strain, the k-resistance can be indicated when using the maximum hydraulic pressure measurement that occurs in the test soil during the test. The torsional cylinder impact shear test provides a unique combination of characteristics. This combination is expected to lead to a wider The in situ method j used can indicate the liquefaction resistance in situ particularly accurately. First, the torsional cylinder impact shear test can apply reasonable tick shear stress to the test soil. Second, the stress has a reasonable high level of stress. Three 'Shear stress results in a reasonably pure shear strain. This combination of properties has its attractiveness. It is believed that liquefaction is mainly caused by shear load. Shear load is usually quite large'. The most common result is large shear strain. Although existing methods have their Importance, but there is no one way Such a combination of properties can reasonably and accurately indicate the liquefaction resistance in situ. For example, using a low strain method, important high strain factors such as relaxation shadows cannot be fully reflected in a shear test using a torsional cylinder. Refer to Figure 9, drill When the hole reaches a specific test depth for sampling and test work, the lower end of the drill assembly 54 can be plugged to prevent the soil below the drill assembly 54 from rising upward into the interior of the assembly. At the test depth, if the soil rises toward the drill, the soil (test Soil) will be disturbed. The test results do not reflect the expected characteristics of undisturbed soil. However, the conventional plunger 52 is still allowed to move when the plunger is ready for the test. The plunger 52 is mainly a solid cylinder, covering the Bored inside the drill. The plunger is removed from the drill assembly 54 by raising the drill rod 56 attached to the plug. During the initial movement of the plunger (indicated by d), the plunger and the soil below Extraction force appeared between A. The extraction force caused the soil below to move with the plunger as indicated by the arrow E, so the test soil moved up to the drill and became dry ^ Paper size㈣CNS Λ4 size (210X297 (Li) --------:--.11---------- Seed clothing ------ 1T ------. ^ (Please read the note on the back first ^^ Please fill in this page again.] Mian Manbu * * Staff of Standards Bureau eliminates cooperation. Printed by the agency A7 Β7 V. Description of invention (9) Disturbance. Now refer to Figure 10 and attach to the special modified drilling rod 70. The drill plunger 58 can reduce the extraction force that occurs between the drill plunger and the soil below during the plunger removal. The plunger is composed of two main components, the directional probe / valve assembly 60 and the housing 62, which can Separated by a predetermined amount. During drilling, when the directional probe / valve assembly 60 was closed by the pressure of the soil below (as shown in Fig. 10), the two components were blocked by the locking wedge 66 and could not rotate relative to each other with the longitudinal axis as the axis. The plunger plays a conventional role. The assembly 60 includes a T-shaped hollow rod 72 screwed to the end 74. The rod 72 is adapted to slide inside the bored hole 76. The channel 78 defines a through-bar 72. The facing surfaces of the assembly 60 and the casing 62 are matching wedge-shaped surfaces. After the drilling assembly drilled to the test depth, the plunger 58 was removed, but during the initial movement of the drilling rod 70, the upper part of the plunger was raised, as shown in Fig. N. This allows the valve to open 'to allow the drilling fluid F (located above the plunger of the cymbal assembly) to flow through the fluid hole 65 through the opening 64 to surround the directional probe / valve assembly 60 and into the soil below the directional probe / valve assembly 60. This reduces the extraction force acting on the underlying soil when the plunger is removed as is known. As a result, the tendency of the soil below the drill to rise when the plunger is removed can be reduced. By inhibiting the soil from rising towards the drill during removal of the plunger from the drill, interference with the test soil can be minimized. Results The single-torque torsion cylinder shear test (for example) more closely reflects the characteristics of undisturbed soil ^ Although the invention is illustrated with a limited number of specific examples, those in the industry understand that numerous modifications and changes can be made. The scope of the patent application, which is intended to be appended, covers all such modifications and changes that fall within the spirit and scope of the present invention.
