Development of Pre Drilling In-Situ Rock Mass Shear Measurement System
摘要
In engineering construction, it is of great significance to calculate the shear strength and internal friction Angle of rock mass. Compared with laboratory test and theoretical analysis, in-situ test can maintain the essential state of rock mass to the maximum extent, and obtain multiple groups of test data conveniently and quickly. The pre drilling in situ rock mass shear measurement system is independently developed. The system is described from the aspects of shear principle, overall design, hardware design and software platform. The system can get the shear strength parameters of rock mass quickly and efficiently, and the linear correlation of test data is high.
