Stability and Comprehensive Treatment Technology of a Tunnel and Multi-sliding-surface-landslide Oblique System
Taking a highway tunnel as the research object,by means of geophysical prospecting,drilling and monitoring,the stability and comprehensive treatment technology of the tunnel and multi-sliding-surface-landslide oblique system are studied.The results show that,there are three sliding surfaces in the landslide,and the stability of the second sliding surface is the lowest,which is the main sliding surface,the landslide is in an unstable state under rainstorm conditions.For the deformed tunnel and multi-sliding-surface-landslide oblique system,the treatment idea of zoning and phased treatment,taking emergency engineering first on the basis of monitoring,combining emergency engineering with permanent engineering,and taking comprehensive prevention and control measures combining various means is put forward.The monitoring data show that the landslide and structure of the tunnel and multi-sliding-surface-landslide oblique system are in a safe state after being treated by comprehensive measures such as back pressure at the landslide toe,steel pipe pile group,anti sliding pile,back pressure in the tunnel,double arch and strengthening lining support parameters.
