利用监测信息 (如位移 )进行优化反演是确定模型参数的有效方法 ,针对三峡永久船闸高边坡 ,通过对一组参数基准值加入一定的扰动量以观察相应的计算位移的变化 ,分析了不同的岩体力学参数对边坡监测点计算位移的敏感度及测点的布置对敏感度的影响·敏感度较大的参数可以通过优化反演求得 ,测点的位置不同 ,该处的计算位移受参数的影响也不同 ,为提高参数的敏感度 ,应对测点进行合理的布置· The optimization inversion using monitoring information (such as displacement) is an effective method to determine the parameters of the model. Aiming at the high slope of the permanent ship lock of the Three Gorges Project, the perturbation of some parameters is added to observe the corresponding change of calculated displacement. Different Rock Mass Mechanics Parameters Sensitivity to Slope Monitoring Point Calculating Displacement and Influence of Measuring Point Arrangement on Sensitivity · Sensitive parameters can be obtained through optimization inversion with different measuring points. Calculation of displacement by the parameters of the impact is also different, in order to improve the sensitivity of the parameters, the measurement points should be reasonable layout ·
