摘要
基坑工程设计是一种风险性较大的系统工程。为了对广州珠江新城I1-8场地基坑设计进行校核,引进了目前广泛使用的强度折减法理论,借助于有限元数值计算方法,对该工程的设计方案进行了验算分析,结果表明:计算得到的土钉内力设计值为142.4kN,边坡稳定安全系数1.736,与原设计方案相比基本一致,原设计方案较为安全,因此该基坑设计方案安全可行。
Foundation pit design is a risking system incheng I 1-8 pit, strength reduced method was used. again. The results indicated that, the axial 1.736 .They were both the same as the force force of and fact engineering. In order to check the design plan of zhujiangx- By using finite element method, the design plan was discussed soil nails was 142.4kN, the buckling safe factor of slope was or in the original plan, so the design plan was safe and reasonable.
