Abstract: In the practice of the landslide investigation, the reliable stability shear strength parameters are very difficult to be obtained from the laboratory testing; whereas, parameters that are from the inverse analysis have higher reliability. Therefore, the inverse analysis method becomes an important method in the landslide stability investigations. This paper introduces a landslide case study in Jiexia Village of Gangkou Town, Xiushui County, Jiangxi Province. Conventional methods for the shear strength determination are compared and the need for the inverse analysis are also discussed. The overall stability of the area has been investigated using inverse analyzed data in the paper. The landslide remediation recommendations and preventive measures are also provided.
