Description
Technical field
The invention belongs to ground experimental provision fields, and in particular to it is a kind of reduction tensioning splitting generate country rock-lining cutting connect
The device of contacting surface further relates to a kind of country rock-lining cutting contact surface method that reduction tensioning splitting generates.
Background technique
Current tunnel excavation mostly uses drill bursting construction, and the stress wave that explosion is emitted generates Radial crack, these cracks
The direction that Local influence Anlysis principal stress can be preferentially parallel to is propagated, i.e., circumferential, and rock mass is thus formd among adjacent shot hole
Splitting surface, generally after the completion of blast working, i.e. progress concrete spraying support, rock mass splitting surface side develops for country rock-lining
Contact surface is built, similar with research rock mass discontinuity, research is important because country rock-lining cutting contact surface that drill bursting construction is formed also has
Meaning, this is a breach for studying country rock and lining cutting contact action.
When studying country rock and lining cutting interaction, contact action is an importance, and connecing between country rock and lining cutting
Contacting surface is the main carriers for the effect that is in contact.Existing research show country rock-lining cutting contact surface mechanical property not only with its two
Side rock mass is related with concrete, also closely related with the configuration of surface of contact surface, to study country rock-lining cutting contact surface mechanics row
For, obtain the relationship between related mechanics parameter, research geometrical morphology and mechanical property it is necessary to a large amount of different surface configurations are unfolded
Country rock-lining cutting contact surface shearing test.But at present at the scene on sampling and indoor reduction country rock-lining cutting contact surface there is also with
Lower difficulty:
1, scene obtains real contact area sample and has difficulties, in particular by the splitting surface formed after drill bursting construction, because
Immediate support is needed, so just being covered by concrete layer when formation, is not easy to obtain splitting surface sample;
2, " nonrepeatability of real contact area test ".Even if having got real contact area sample at the scene, room is carried out with it
Interior compression or shearing test, contact surface destroys at once after test, can not remold, and changes one group of contact surface and is tested, and because of every group
Contact surface specimen surface form is different, it is different to lead to test result, therefore there is a problem of that laboratory test is not reproducible;
3, " regular angular simulation cannot reflect real topography feature ", in order to solve above-mentioned two problems, numerous scholars study system
" standard angle contact surface " is made.This production country rock-lining cutting contact surface method is to be cut into zigzag on one block of steel plate
Regular angular, usually have 30 °, 45 °, 60 ° etc., then in the contact surface steel plate model side (single side sawtooth) of production or two sides
(two-sided sawtooth) casting concrete or analog material prepare the country rock for laboratory test-lining cutting contact surface sample.But this
The regular angular set a bit can not reflect the geometrical characteristic of real contact area, only a kind of covert equivalent and replace, and recessed
The contact surface time of day of convex injustice is not only to have differences on geometrical morphology, also there is relatively large distance on mechanical behavior.
4, country rock-lining cutting contact surface generates response due to by external force, and the direction of external force is not necessarily flat
Row is in contact surface, and the external force size acted in contact surface two sides country rock and lining cutting can also have differences, therefore indoors
When simulation test, need to apply active force of different sizes on the rock of contact surface two sides, and this is seldom in the conventional method
See, because the effect of power be it is mutual, contact surface two sides apply active force of different sizes and are not easy to realize.

Smashing simulation filler material or being vibrated using machine keeps simulation filler material closely knit, and box mold is dismantled in maintenance two days later, takes out country rock-lining
It builds Soil-structure Interaction Model (1), obtains left side sample and right side sample, be combined into one left side sample and right side sample to obtain sample.
