借助多目标非线性规划函数思想,结合长株潭城际高铁II标湘府路车站基坑工程,在反演过程中利用多种监测项目的数据,以求能够获得比较准确的反演参数。通过对比单目标函数反演力学参数计算结果、多目标函数反演力学参数计算结果及现场实际监测值,发现多目标函数获得的反演力学参数输入到数值分析软件中得到的结果更接近于现场实际监测结果,说明在参数反演分析过程中,利用施工中多元监测数据的信息量越大,获得的反演参数的可靠性越好。
With the idea of multi-objective nonlinear programming function, combined with the foundation pit project of Changsha-Zhuzhou-Xiangtan inter-city high-speed rail II Xiangfufu station, the data of various monitoring projects are used in the inversion process in order to obtain more accurate inversion parameters. By comparing the calculation results of the single objective function inversion mechanics parameters, the multi-objective function inversion mechanics parameters and the actual monitoring values, it is found that the inversion mechanics parameters obtained by the multi-objective function are input to the numerical analysis software and the results are closer to the scene The actual monitoring results show that in the process of parameter inversion analysis, the greater the amount of information using multivariate monitoring data in construction, the better the reliability of obtained inversion parameters.
