METHOD FOR TESTING SOFT ROCK GROUND STRESS IN EXPLORATION ENGINEERING
The invention discloses a method for testing soft rock ground stress in exploration engineering, which is characterized in, it comprises the following steps: (1) drill holes in the surrounding rock mass of the soft rock roadway; (2) according to the number of measuring points; (3) put a stress sensor into the drill hole; (4) insert grouting pipe to grouting between the stress sensor and the drill hole wall; (5) repeat steps (3)~(4); (6) calculate the angle and position of each sensor; (7) calculate the internal stress component of each sensor; (8) obtain the secondary stress of the drill hole in an iterative convergence method; (9) retrieve the original rock stress field before the excavated roadway. Compared with the prior art, the invention has the advantages of collecting various force data in the rock and soil by means of multi-point and multi-position measurement, summing up the data, and obtaining the stress distribution inside the rock and soil through calculation and deduction, it is convenient for construction and saves a lot of time and economic investment for the construction of geotechnical materials with uneven stress distribution that are difficult to measure. drill holes in the surrounding rock mass of the soft rock roadway make the same number of stress sensors put stress sensor into the drill hole, record the depth position of the sensor inside the hole insert grouting pipe to grouting between the stress sensor and the drill hole wall repeat the last two steps until all the sensors are placed in the drill hole calculate the angle and position of each sensor calculate the internal stress component of each sensor obtain the secondary stress of the drill hole in an iterative convergence method retrieve the original rock stress field before the excavated roadway Figure 1
