Description

Recover the deep soft rock terrestrial stress method of testing and the device of principle based on flow stress
Technical field
The invention belongs to the ground field of measuring technique, relate to a kind of terrestrial stress method of testing that is applicable to the deep soft rock particularly, also relate to a kind of observation device that is used for this method of testing simultaneously.
 
Background technology
The colliery deep wall rock is broken mostly weak, and mechanical strength is low.The Validity Test that in such loose and soft surrounding rock, adopts method of testing commonly used at present to carry out terrestrial stress is very difficult, has significant limitation and measuring error.Hydraulic fracturing extensively to adopt in water conservancy and hydropower and the traffic tunnel engineering is an example; Its boring packer need possess good water-stop property under high hydraulic pressure; Integrality to rock mass has proposed harsh requirement, is not suitable for the broken weak rock mass that deep, colliery joint fissure is grown.And this method can only confirm to be essentially the two-dimensional stress measuring method perpendicular to the major principal stress and the least principal stress of boring in the plane, is difficult to obtain the three-dimensional stress state of measuring point.
Another kind of common testing methods is a stress relief method.For the calculated stress value, at first must confirm rock mass mechanical property parameter (like elastic modulus E and Poisson ratio μ etc.) and the mutual relationship of survey physical quantity (strain) and stress.As far as containing the soft rock mass in a large amount of cracks; Suffered stress state, rock mass test specimen size and the shape of mechanical property parameters such as its elastic modulus E, Poisson ratio μ and rock mass is closely related; The rock mass test specimen of different stress states, different sizes, the elastic modulus E that test draws and the numerical value of Poisson ratio μ can differ several times even more than ten times.When this just requires to adopt stress relief method test terrestrial stress, must obtain the elastic modulus that obtains core under the stress state above the complete core of sensor length (at least greater than 30cm) and thick cyclinder outer wall uniform-compression.Mostly deep, colliery soft rock mass is argillaceous agglutination; Stood the effect of high-ground stress; Get and receive current scour and the strong off-load effect of stress in the core process, in most cases company commander's degree short core of reaching 10cm also is difficult to obtain, thereby is difficult to obtain mechanics parameter through the uniaxial compression experiment.Therefore, stress relief method is difficult to carry out in the loose and soft surrounding rock of deep, colliery.Other rock mass terrestrial stress method of testing such as acoustic-emission etc., not only can't be competent at the terrestrial stress test of loose and soft surrounding rock, and can't record the initial stress in principle.
Do not see at present the disclosed observation procedure and the device that can in the loose wall rock of deep, colliery, carry out Validity Test as yet.Existing direct measuring equipment mainly is the pressure cell that is applied in the soil body; Such as the disclosed a kind of resistance-strain pressing shaft type soil pressure cell of Chinese utility model patent (application number 03212896); The resistance strain gage that utilizes the cyclic spring diaphragm to be covered with writes down the compressive deformation of flexible sheet, reaches the purpose of measuring vertical in the diaphragm directional pressure.The two film waterproofing pressure boxes of China's utility model patent (application number 201120082368.9) disclosed a kind of inflatable type are provided with waterproof grommet between the power transmission film of pressure and stressed film, reach the purpose of waterproof, steady testing pressure.These observation devices and method only can be measured unidirectional pressure, terrestrial stress that therefore all can not a certain measuring point of Validity Test.
 
Summary of the invention
Technical matters to be solved by this invention has been to provide a kind of earth stress measuring method that is applicable to soft rock.Through this method, can directly measure and obtain the inner stress value of country rock, and can obtain observation data for a long time, be used for the research of soft rock terrestrial stress distribution of deep, colliery and stability of surrounding rock.
 
A kind of deep soft rock terrestrial stress method of testing based on flow stress recovery principle may further comprise the steps:
(1) in the internal drilling of country rock of soft rock roadway body to the test point place;
(2) two triaxial pressure boxes are adjacent to be fixed on the connecting link, deliver to the test point place; Said triaxial pressure box has mutually perpendicular three workplaces, notes the direction cosine between any two workplace normal directions between two triaxial pressure boxes, and should value all must not be 1; On two each workplaces of triaxial pressure box the device of mensuration to compressive stress is installed, this device is connected with the outer readout instrument of boring through data line;
(3) slip casting is implemented in boring, after filling up boring is sealed;
(4) after slurries solidify, from readout instrument, constantly read force value, after pending data is stable, survey two triaxial pressure boxes in six pressure data substitution terrestrial stress test philosophy formula, draw the terrestrial stress at this test point place.
Adopt long-time interior enforcement of said method and repeatedly measured, just can obtain the terrestrial stress evolution data of this test point.
The direction cosine of any two workplaces all must not be 1 between two triaxial pressure boxes recited above, are meant that the normal direction of any two workplaces between two triaxial pressure boxes does not overlap, and are not parallel in other words.
The present invention in fact also provides a kind of geostress survey device, comprises connecting link, and two triaxial pressure boxes are adjacent to be fixed on the connecting link; Said triaxial pressure box has mutually perpendicular three workplaces, and the direction cosine of any two workplaces are not 1 between two triaxial pressure boxes; On two each workplaces of triaxial pressure box the device of mensuration to compressive stress is installed, this device is connected with the outer readout instrument of boring through data line.
The mensuration of installing on two each workplaces of triaxial pressure box can adopt any equipment known in the art, such as what background technology provided to the device of compressive stress; Can also be the type vibration wire structure of knowing altogether in the surveying instrument field; Comprise the steel flexible sheet that is positioned at workplace, be fixed with two steel cylinders below the flexible sheet, be fixed with string wire between two cylinders; Be with coil on the string wire, coil connects data line.
Can also be the resistance-strain type structure.Comprise the flexible sheet that is positioned at workplace, central authorities are fixed with resistance strain gage below the flexible sheet, and resistance strain gage links to each other with readout instrument through data line.
Mention two triaxial pressure boxes above and be adjacent to be fixed on the connecting link, these two triaxial pressure boxes are one group of triaxial pressure box.In fact can also connect many group triaxial pressure boxes on the connecting link, can measure terrestrial stress for simultaneously a plurality of test points like this.
As a kind of preferred, said connecting link can be for hollow, and described data line is connected with the outer readout instrument of boring via the cavity of connecting link.
