【摘要】 文中首先对深基坑工程变形控制进行了详细的论述 ,提出了基坑有效系数、有效区、失效区、临界线的新概念 ,同时提出了变形控制参考标准和经济有效的变形控制对策。简介了自制的深基坑工程变形控制优化设计及其有限元数值模拟系统 (SDCDEFEM)。利用该系统 ,对影响基坑变形的各因素进行了有限元数值模拟分析 ,得出了简明估算深基坑最大变形及其位置的统计关系式。更多还原

【Abstract】 Deformation control of deep excavation pits is firstly introduced in detail,and new conceptions of effective coefficient,effective area,no-effective area and critical line,including the referential criteria and economic-effective measures of deformation control,have been put forward.The system of the optimized design with deformation control and the numerical simulation with finite element method of deep excavation engineering(SDCDEFEM) is introduced.Factors influencing its deformation are analyzed by the system,the statistic formula estimating maximum deformation and its place have been obtained.更多还原
