边坡加固工程岩土设计研究--以福州市台江区某银行营业部南侧工程为例

Study on geotechnical design of slope reinforcement engineering--Take the south side project of the business department of a bank in Taijiang District of Fuzhou city as an example

以福州市某已坍塌的边坡为例,充分考虑地理位置、周边环境、地下水、造价及工期等影响因素,对比研究不同支护方式在该边坡加固工程中的适用性,表明锚杆挡土墙结合钢管桩在已坍塌边坡加固的技术优点,并强调合理安排岩土施工工序对加固工程的重要性。施工及监测结果表明:“锚杆挡土墙+钢管桩”边坡加固方案合理可行,节省造价工期,适应于已坍塌的建筑边坡加固工程。

In a case study,the supporting technique of anchored retaining wall with ribbed plate and steel pipe pile was implemented to a collapsed slope in Fuzhou.By taking geographical location,ambient environment,groundwater,project cost and time limit into account,our analyses reveal the technical advantages of anchor retaining wall and steel pipe pile in reinforcing the collapsed slope,emphasizing the importance of reasonable arrangement of geotechnical construction procedure.The construction and monitoring results show that anchor retaining wall with steel pipe pile scheme is feasible,economical,and timesaving,well suited for einforcement of the collapsed slope.
