| Abstract: | 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. |
