西南某工程边坡支护方案案例分析及理正计算可靠性分析

Slope Support Scheme of Some Project in Southwest and Reliability Analysis of Lizheng Calculation

边坡区斜坡为粉质粘土覆盖,下部为基岩层;部分地段为平台。斜坡坡角15°~20°左右。场坪标高541.50~544.50m,场地整平后形成长161m,高5.7~10.5m的土岩混合挖方边坡。距离拟建18层高建筑物8.3m,边坡破坏后果严重。确保边坡在工程年限内,出现天然,暴雨等作用下,不发生浅部整体滑动;确保小区居民生命财产安全;选取针对性强的"桩板式挡墙"工程措施和治理方案,利用理正计算软件对工程边坡支护方案设计,分析评价方案的可行性,通过对理正软件的计算结果进行复核对比分析,优化软件计算结果。对类似工程具有一定参考借鉴作用。

The studied slope is composed of bedrock and silty clay cover with slope angle 15°~20°. The field level is 161 m long and 5.7-10.5 m high with 541.50-544.50 m above sea level and 8.3 m from proposed 18-storey building. For security purposes, engineering measures and treatment scheme of "pile plate retaining wall" is used. Engineering slope support scheme is designed by means of the series software of the Lizheng Geological Structure Designing.
