Description
Technical field
The present invention relates to a kind of measuring method of the Deformation Module of Rock Mass of different depth.Belong to rock engineering field.
Background technology
When rock engineering Stability Analysis of The Surrounding Rock and design of its support is carried out, it must be determined that the mechanical characteristic of surrounding rock body,
The determination of wherein deformation modulus is particularly important.Common practice is to sample at the scene, after standard specimen is processed into laboratory, is entered
Row compression test measures deformation modulus, but the deformation modulus for now measuring can only represent the deformation modulus of small yardstick rock,
But there are numerous cracks in live large scale rock mass, had a strong impact on rock mass in the forming process of long-term geologic process, often
Globality, cause the mechanical characteristic of Test in Situ and the mechanical characteristic of rock that there is larger gap, the test of deformation modulus
Result also differs greatly with live large scale rock mass.Therefore, rock mass mechanics performance test is directly carried out at the scene, it has also become domestic
The hot issue of outer rock mechanics.The great advantage of on-the-spot test is small to rock mass disturbance, and the day of rock mass is maintained as much as possible
Right structure and environmental structure, the Mechanics Parameters of Rock Mass measured are more directly perceived, accurate, and its shortcoming is then that testing equipment is heavy, operates
It is complicated, long in time limit, costly.
Scene deformation modulus experiment at present is mainly bearing plate method, can be divided into rigid bearing plate method and flexible load-bearing plate method.
Flexible load-bearing plate method can be divided into double pillow methods, four pillow methods, annular pillow method and centre bore method again.Rigid bearing plate method is used China more,
The method is applied to rock mass at different levels, and its advantage is easy, directly perceived, the stress and deformation behaviour of energy preferably simulation rock mass.
But rigid bearing plate method needs the counter-force for providing larger, is generally used under open-air condition, and test apparatus is heavy,
Process of the test takes time and effort, and experimentation cost is also very high.In addition, bearing plate method all assumes that the following rock mass of pressurized plane is half nothing
Limit, uniform, continuous, isotropic medium, it is public with the Bu Xinniesike set up in the case where being acted on by concentrated force with Into Semi-infinite Homogeneous body
The formula derived based on formula calculates deformation modulus.This measuring method is suitable, but engineering for continuous media rock mass
Rock mass in practice contains crack, fault belt, weak intercalated layer etc., sometimes can also be due to the shadow of the effects such as excavation and explosion
Ring, produce damage, destroy the integrality of rock mass.Therefore, traditional bearing plate method cannot reflect structure characteristics of rock mass pair
In the influence of deformation modulus.
The content of the invention
The technical problem to be solved in the present invention is：A kind of measuring method of the Deformation Module of Rock Mass of different depth is provided, should
It is easy to implement that the equipment that method is used should meet lightweight, Assembling, can be in most engineering-environment especially underground work
Measured in journey, and can realize being measured while the deformation modulus in different depth rock mass, to avoid crack, tomography from breaking
The influence to measurement result such as broken band, weak intercalated layer.
The technical solution adopted in the present invention is：A kind of measuring method of the Deformation Module of Rock Mass of different depth, its feature
It is to comprise the following steps：
1st, the arrangement of deformation modulus measurement point, selection can fully represent the various lithology in experiment location, have to construction quality
The rock mass of material impact is measured；
2nd, in selected measurement point arrangement test hole, test Dong Dong footpaths are 2~3m；
3rd, polishing cleaning carried out to the pressure-bearing surface for testing hole, the Impact direction of measurement point preferably with engineering rock mass actual loading side
To consistent；
4th, loading device is arranged in test hole, loading device includes jack, oil pump, pressure gauge, bearing plate and multiple spot
Displacement meter, wherein board plate suqare are not less than 0.5m2, jack oil pressure maximum is 10MPa；
5th, 1 hole footpath is respectively drilled through on two pressure-bearing surfaces in test hole for the drilling of 90mm and is rinsed well, be put into multiple spot
Displacement meter, and carrying out grouting makes multipoint displacement meter be bonded closely with periphery rock mass, the measuring point of multipoint displacement meter is with interval of 0.5m
One measuring point of arrangement；
6th, using the pump switch control oil pump output pressure being connected with oil pump, apply step by step since 1MPa, every grade of increasing
Plus 1MPa, until 10MPa, the pressure of oil pump output is delivered to bearing plate by jack, and power is acted on into week using bearing plate
The rock mass on side.
The beneficial effects of the invention are as follows：This measuring method is measured while realizing Deformation Module of Rock Mass at different depth,
Test process interference is few, it is to avoid excavates the disturbance to rock mass, and shortens time of measuring, measurement result is more accurate, and section
About expense, installs simple, easy to operate, is easy to live popularization.
Brief description of the drawings
Fig. 1 is scheme of installation of the invention.
Specific embodiment
As shown in figure 1, the measuring method of the Deformation Module of Rock Mass of the present embodiment different depth, step is as follows：
1st, the arrangement of deformation modulus measurement point, selection can fully represent the various lithology in experiment location, have to construction quality
The rock mass 8 of material impact is measured；
2nd, in selected measurement point arrangement test hole 1, the test hole footpath of hole 1 is 2~3m, it is ensured that survey crew has enough
Operating space, and loading device can be put into；
3rd, polishing cleaning is carried out to the pressure-bearing surface 1-1 for testing hole 1, it is ensured that the power that loading device is produced can be passed equably
Enter in rock mass 8, the Impact direction of measurement point is preferably consistent with engineering rock mass actual loading direction；
