Description
Technical field
This utility model is related to indoor soil mechanics testing equipment, more particularly to the application of resonance column device.
Background technology
The modulus at rapid deformation of the soil body and damping ratio analyze the important parameter of design as geotechnical engineering problems, not only in seismic site
There is pivotal role in the soil body dynamical problem analyses such as analysis, Mechanical Fundamentals design, also have in some static(al) deformation analyses
Important function.Therefore the research of soil body modulus at rapid deformation and damping ratio is all the hot issue in Geotechnical Engineering field all the time.The soil body
Modulus at rapid deformation and the measure of damping ratio mainly have two kinds of devices of live in-situ test and laboratory test.
And determined in the dynamic modulus of soil and all devices of damping ratio indoors, resonant column test is a kind of the most frequently used dress
Put, and be considered as to determine the most reliable device of soil body modulus of shearing.Stokoe types Resonant Column has measurement former due to which
Reason clearly, torsion cut-off-die block can be combined the advantage such as use, be a kind of resonance column device being most widely used, but due to 1. its drive
The moment of torsion that system can apply is limited；2. the reason such as drive disk upper magnet range of movement in coil is limited, which tests strain model
Enclose less, it is considered that test strain maximum can be to 1.5%.Which limits researcher and explore dynamic trait under big strained situation
Characteristic is cut with torsion.For studying the dynamic parameters of the soil body in the range of large strain, researchers are using dynamic triaxial or dynamic single
Cutting carries out the test of soil body modulus at rapid deformation and damping.But as its test philosophy and sample with Resonant Column is difficult to ensure that in itself completely
Identical, therefore greatly reduce the comparative of two kinds of tests.Therefore, the test range of strain for improving Stokoe type Resonant Columns has
Important meaning.
Utility model content
In view of the deficiency that background technology is present, technical problem to be solved in the utility model is to provide a kind of increase resonance
The device of range of strain tested by post, can effectively increase the scope that resonance column device produces strain, expands the research range of resonance instrument, behaviour
Facilitate, low cost, and do not change original Resonant Column drive system.
This utility model adopts the following technical scheme that to complete：A kind of increase Resonant Column tests the dress of range of strain
Put, including base, permeable stone and top cap, the permeable stone includes upper dankness stone and lower permeable stone, the base and lower permeable stone
Between be provided with cylinder, be provided with multiple through holes through cylinder on the cylinder, lower permeable stone is corresponding with base to be led to
The position in hole is respectively arranged with unthreaded hole and screwed hole, and bolt of long stem sequentially passes through unthreaded hole, through hole and is tightly fastened company with screwed hole
Connect, on the cylinder, be provided with multiple permeable holes through cylinder, soil sample is arranged between upper dankness stone and lower permeable stone,
Top cap is pressed with the top of upper dankness stone.
The cylinder top end and bottom are provided with annular seal groove, are configured with sealing ring in seal groove.
The cylinder diameter is identical with base diameter, and the height of cylinder needs to arrange according to test.
By the base of rising sample in this utility model, reduce sample ratio of height to diameter to reach, do not increasing drivetrain
System moment of torsion, the test that can obtain big strain in the range of limited magnet movement, can effectively increase resonance column device and produce strain
Scope, expand the research range of resonance instrument, easy to operate, low cost, and do not change original Resonant Column drive system.

Specific embodiment
Accompanying drawing illustrates the technical solution of the utility model and embodiment, further describes in fact in conjunction with accompanying drawing below
Apply each relevant details of example.
With reference to shown in Fig. 1, Fig. 2, Fig. 3, a kind of increase Resonant Column that this utility model is provided tests the device of range of strain,
Including base 1, permeable stone and top cap 2, the permeable stone includes upper dankness stone 3 and lower permeable stone 4, and the base 1 is permeable with
Cylinder 5 is provided between stone 4, is provided with multiple through holes 6 through cylinder on the cylinder 5, lower permeable stone 4 and corresponding
The position of through hole 6 is provided with unthreaded hole 7, and the position of the corresponding through hole 6 of base 1 is provided with screwed hole 8, and bolt of long stem 9 sequentially passes through light
Hole 7, through hole 6 being tightly fastened with screwed hole 8 is connected, and is provided with multiple permeable holes 10 through cylinder on the cylinder 5,
Soil sample 11 is arranged between upper dankness stone 3 and lower permeable stone 4, is pressed with top cap 2 at the top of upper dankness stone 3,5 top of the cylinder and
Bottom is provided with annular seal groove 12, is configured with sealing ring 13 in seal groove 12, and sealing ring 13 ensures base 1 and lower permeable stone
Air-tightness between 4,5 diameter of the cylinder are identical with 1 diameter of base, and the height of cylinder 5 needs to arrange according to test,
After tightening bolt of long stem 9, you can sample preparation, after the completion of sample preparation, original Resonant Column drive system is installed, you can tested.
This utility model with 1 equal diameter of base and has the cylinder 5 of certain altitude lifting the height of base using one,
To obtain the sample of less ratio of height to diameter, do not increase drive system moment of torsion, in the range of the limited magnet movement by obtain and greatly should
The test of change, can effectively increase the scope that resonance column device produces strain, expand the research range of resonance instrument, easy to operate, cost
Low, and do not change original Resonant Column drive system.
