- 摘要:
- 千河村滑坡位于普光气田地面集输工程拟建场区内,其稳定性关系到拟建工程的安全。文章在对滑坡体进行地质调查的基础上,运用数值模拟手段,分析了其稳定性。结果表明:滑坡在天然状态下处于基本稳定状态,在50年一遇暴雨条件下处于欠稳定状态。据此提出:后河大桥及后河天然气管道悬索跨越应重新选址;如工程不另选址,则应根据滑坡纵向剩余下滑力的大小及分布,采用两级抗滑桩支挡进行防治。
Landslide risk zone in Qianhe Village is located in the planned construction area of Puguang Gas Field surface gathering and transportation project, and its stability is related to the safety of the planned project. Based on the geological investigation on the landslide mass, the numerical simulation is used to analyze its stability. The results show that the landslide is in basic stable state in natural conditions and in understable state in the torrential rain condition of thirty year return period. Hereby, the landslide control measures are put forward,namely the sites of Houhe Bgidge and Houhe pipeline stayed-cable crossing need choosing again, otherwise the two-stage anti-slide piles should be used as support according to the magnitude and distribution of longitudinal surplus downslide forces of the landslide.2012,3(3): 24-28 收稿日期：2011-3-12DOI：10.3969/j.issn.1001-2206.2012.03.007作者简介：张卫明(1968- ),男,重庆忠县人,高级工程师,1990年本科毕业于华北水利水电学院水文地质与工程地质专业,2002年获中国海洋大学环境工程(岩土)专业硕士学位,长期从事工程勘察技术和管理工作.参考文献：
