Stability Analysis and Treatment Measures of Retrogressive Landslide in Xinluo District,Longyan City,Fujian Province
Retrogressive landslide is a common type of landslide in engineering construction in mountainous areas.It is often caused by sliding after rainstorm or manual excavation and slope cutting,and will first slip and extrude at the foot of the slope,which is a threat to the safety of the project site.Taking an engineering landslide in Fujian Province as an example.The stability of the landslide in different engineering stages under natural and rainstorm conditions is analyzed by using the strength reduction method and the transmission coefficient method.The corresponding treatment measures are proposed and the feasibility study is carried out.The results show that the landslide is unstable under the rainstorm condition after excavation.The comprehensive treatment measures are stable under both natural conditions and rainstorm conditions,which indicates that the safety requirements are met.The research results has certain reference value for similar projects.
