Research on rheologic dynamics for geologic disasters of soft rock-soil under dynamic loading;

Combining with the facts of geologic disasters of soft rock-soil in recent years in Chinas,the author discusses the train of thoughts and application foreground of the research on sudden geologic disasters of soft rock-soil disaster and their monitoring and prediction by use of the theory and method of dynamic rheologic mechanics.

Influence of weak rock on stress-deformation of auxiliary dam 1~# of Xilongchi upper reservoir;

To reinforce slope of weak rock has been tough problem during rock soil engineering, especially for sl-ope consisting of broken weak rock.

Large section tunnel construction technology in fractured weak strata;

Large-section room construction technique in weak strata in Jinchuan mine area

Analysis on the treatment of the lining cracks of the shallow covered slope multi-arch tunnel in weak surrounding rock;

Construction technology of triple-line large-span weak surrounding rock of expressway;

Application of smooth blasting in weak surrounding rock excavation for the Aketage Mountain water conveyance tunnel;

Discussion on the critical technique in the construction oflong-span flat tunnel at the weak wall rock;

Research purposes:The structure is loose and the stability of wall rock is very bad because the opening body of the tunnel crosses the weak wall rock laterally,so the technical researches are done on the support in course of excavation of weak wall rock.

Research purposes: The researches are done on matching rapid construction technology with machinery for highland stressed weak wall rock tunnel for the purposes of setting performance of large-sized machinery in construction of highland stressed weak wall rock tunnel and providing mature and high efficient mode of matching construction machinery with construction technology.
