变形岩体软弱破裂带的处理技术

Treatment of Weak and Cracked Area in Deformed Rock Mass

摘要:

在研究完成变形岩体软弱破裂带可灌性的基础上，采用旋喷注浆技术进行直接加固处理，提高破裂带的内聚力和内摩擦角。实践证明，抑制了岩体的变形，防止了滑坡的产生

Abstract:

On the basis of feasibility test on weak and cracked area in deformed rock mass, direct reinforcement is made by jetgrouting to improve both cohesion and inner frictional angle of the rock mass. It is proved that rock deformation is hold back, and the landslide is avoided.
