| 摘 要： | 为了能够准确地确定m值,必须合理选择计算模型.采用弹性地基梁法,结合现场多支撑动态开挖的过程,建立了有约束非线性最优化设计模型.通过以实测与计算位移的相对残差平方和最小为目标,首先根据实测位移建立参数反分析的目标函数,然后采用Matlab有约束非线性优化技术对其进行优化,以达到分阶段多层动态施工反分析的目的,从而使所得...

| Abstract: | In order to accurately determine the m value,a reasonable calculation model must be chosen.Combining with support for dynamic multi-braced excavation process,the constrained nonlinear design model is established based on the elastic foundation beam method.Taking the minimum of relative residual sum of squares of measured and calculated displacement as the goal,the objective function of parameters of the back-analysis is established according to the measured data,and then the objective function is optimized ... |
