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。
In the practice of landslide exploration engineering, it is very difficult to get the accurate shear parameters of soil in the soil test by the geotechnical test method. However, the anti-shear parameters obtained by the inversion method are more reliable, which is an important method of landslide analysis. Through the introduction of the example of the landslide project in the boundary area of Xijia Village of Port Town, Xiuqian County, the commonly used numerical method of landslide soil parameters is contrasted. The necessity of inversion calculation of shear parameters is discussed. The shear parameters, Landslide stability is analyzed. In view of the peculiarity of landslide hazards, this landslide prevention and control measures are discussed, and the monitoring and early warning prevention and control plan is put forward. Compared with the control project, the scheme saves landslide prevention investment.
