山区高速公路边坡滑坡处治探讨

Discussion on Treatment of Side Slope Landslide in Mountainous Expressway

山区高速公路的高填、深切路段较多,且受小区域气候条件影响明显,施工自然条件和环境复杂,特别是高切方边坡施工要做到防护紧跟,监测及时,对施工方案及时进行动态优化,并充分利用专业的地质勘察,确定高大边坡的综合处治方案,达到一次根治,不留后患的目标,为施工安全和通车运营安全打下良好基础。结合本人参建的湖南省张桑高速公路第三合同段一处路堑高边坡,谈谈边坡处治方案的确定及其实施的具体流程。

There are many high-filled and deep-cut sections in mountainous highways, which are affected by the climatic conditions in a small area. The natural conditions and environment of the construction are complex. In particular, the construction of high-cutting side slopes should be protected closely and monitored in a timely manner. The plan should be dynamically optimized in a timely manner, and the professional geological survey should be fully utilized to determine the comprehensive treatment plan of the high slopes, to achieve a radical cure, leaving no future problems, thus laying a good foundation for construction safety and opening operation safety. Based on a high slope of the third contract section of Zhangsang Expressway in Hunan Province, this paper discussed the determination of the treatment plan for the slope and the specific procedures for its implementation.
