福建平和县西环路滑坡防治工程勘察实践与稳定性分析

Site investigation and stability analysis for landslide controlalong Xihuan Road, Pinghe County, Fujian Province

摘要:

滑坡是重大地质灾害之一，严重危害着人类的生命和财产安全。滑坡防治工程勘察是滑坡防治设计的重要基础工作。本文针对福建省平和县西环路滑坡防治工程开展了滑坡区工程地质测绘与调查，结合工程地质钻探成果，分析了滑坡的成因、滑坡稳定性计算及评价，提出了合理的防治措施。推测滑动面位置，确定岩土设计参数，选择合适的安全系数，对滑坡防治工程的综合治理至关重要。

Abstract:

Landslide is one of the major geological hazards which seriously endangers the safety of human life and property. Site investigation for landslide prevention and control is important basic work in landslide prevention and control design. In this paper, the engineering geological surveying and investigation of the landslide area were carried out for the Pinghe County Xihuan Road landslide prevention and control project in Fujian Province. With engineering geological drilling results, the cause of landslides, and the calculation and evaluation of landslide stability were analyzed with proper prevention measures proposed. Inferring the position of the sliding surface, determining the geotechnical design parameters, and selecting the appropriate safety factor are very important for comprehensive prevention and control of landslides.
