Application Abstract: Up to July 2020,Project 4"The evolution mechanism and design key technologies of major landslide-pile-anchor system"has reached its interim goals.Detailed works include:Researchers conducted the research on the investigation and analysis of the Dabaoshan landslide in Jianshi County,Enshi City,Hubei Province and the Baijiabao landslide in Zigui County.Based on the physical model test of the pile-anchor reinforced landslide,the study on the internal force and deformation law of the pile-anchor structure,and the mechanism of the synergy between the pile-anchor and surrounding rock mass have been completed.Meanwhile,through the dynamic centrifugal test,the study on the response law of the landslide-pile-anchor system under dynamic load,and the influence law of the dynamic characteristics of the landslide-pile-anchor system based on the large-scale shaking table test have been completed.Moreover,through the rheological test of the anchoring interface,the evaluation of the multi-parameter time-dependent stability of the major landslide-pile-anchor system based on the rheological properties of the rock and soil has been analyzed.Furthermore,combined with the physical model test and numerical analysis,the research on co-evolution characteristics of multi-parameter information of major landslide-pile-anchor system has been achieved.
