摘要： 在滑坡勘查工程实践中，土工试验方法很难取得滑带土的准确抗剪参数，而反演计算方法得出的抗剪参数可靠性较高，是滑坡分析的重要方法。通过对修水县港口镇界下村滑坡工程实例的介绍，对比了滑坡常用的滑带土参数取值方法，讨论了抗剪参数反演计算的必要性，通过反演计算得出抗剪参数，对滑坡稳定性进行了分析。针对滑坡危害对象的特殊性，讨论该滑坡防治对策，提出了监测预警的防治方案，相比治理工程，该方案节约了滑坡防治投资。

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.
