摘　　要：针对填土边坡高支挡结构设计和施工,以深圳市光明区某新建项目临近边坡为研究对象,采用工程类比法、理论计算和数值计算等方法分析边坡稳定性特征,提出控制边坡稳定安全的治理措施,并对治理前后边坡的稳定性进行计算,提出保证边坡稳定性的现场监测方案和指标。研究结果表明,复杂地质条件填土高边坡经多种支护型式分析比较,优选合理的支挡结构型式,经过设计施工治理,通过施工期间监测数据显示,边坡施工过程中安全可控,支挡结构施工完毕,边坡达到安全稳定状态,所提出的设计方案是合理的。研究结果可为类似地层条件下高边坡支挡加固研究提供参考,对复杂地质条件下高边坡的支挡结构设计施工研究具有重要意义。This paper presents a case history of the design and construction aspects of a high retaining structure in Guangming District,Shenzhen.The slope stability problems before and after the mitigations are discussed with engineering analog,theoretical approach and numerical analysis approaches.The slope stability mitigation recommendations are proposed and the construction monitoring program and criteria are also presented.The results indicate that,the optimum retaining structure is selected from the various feasible retaining walls.After the design and construction,the monitoring data indicate that the slelected wall type is safe and stable.The completed structure is also stable.
