灌注桩结合三轴止水及内支撑的基坑围护设计
摘要:深基坑是一项理论复杂,学科综合性较高及风险较大的工程。工程中经常出现支撑体系失稳、围护结构失稳、坑壁漏水、坑底隆起等现象。以上海某深基坑工程为对象,分析了深基坑围护方案的选型要点,总结了深基坑围护设计中关键的计算与验算内容。最后对比分析了设计计算结果与实际监测数据结果,证明了所采取的围护形式的有效性,希望能为今后类似工程提供一些借鉴和参考。
Abstract:Deep foundation pit is a high-risk project, in which the theories are complex and discipline is highly comprehensive. It often appears bracing system instability, retaining structure instability, pit wall leaking , bottom uplift and so on. Combined with a project example in Shanghai, the main points of selecting scheme of foundation pit support were analyzed. And the key calculations and checking content in the design of retaining structure are Summisized. Finally, design calculation results and the practical monitoring data results are compared. The conclusion had proved the effectiveness of retaining form. It provides some suggestions for same type of deep foundation pit projects.
