深基坑工程变形控制与有限元数值模拟分析

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，提出了深基坑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）。利用该系统及应用实例分析，得出了简明估算深基坑最大变形及其位置的统计关系式。

DEFORMATION CONTROL OF DEEP EXCAVATION ENGINEERING AND ANALYSIS OF NUMERICAL SIMULATION WITH FINITE ELEMENT METHOD

The authors firstly introduce deformation control of deep excavation engineering in detail, and put forward new conceptions of effective coefficient, effective area, no-effective area, critical line, the referential criteria and economic-effective measures of deformation control. It is briefly introduced for the self-made system of the optimized design with deformation control of deep excavation engineering and the numerical simulation with finite element method (SDCDEFEM) to be. Factors influencing its deformation are analyzed by the system, the statistics and analyses of measured and simulated data of maximum deformation (settlement, displacement, swell) and its place have been done, and the statistic formula estimating maximum deformation and its place have been obtained.
