摘要

岩土工程本身的复杂性使岩土工程的三维模型分析结果与实际有一定的误差。利用已有的工程反馈资料，对模型参数进行反演分析。修正易调整的误差因素，来弥补不易调整的误差因素，将模型计算结果的最终误差降到最小。将得到的反演参数用于下一阶段的模型分析，由此获得的三维计算结果更接近真实值。

Abstract

The complexity of geotechnical engineering makes that there must be deviation in the 3D numerical analytical result from the reality. We analyze those deviations

feed back the 3D model with the coupling data and get the parameters adjusted. That is to say that we adjust the easily adjusted factors which result in the inaccuracy for the uneasily adjusted ones; and make the inaccuracy of 3D numerical analytical result to the minimum. We can use the adjusted parameters in the next analytical model

and will get the more accurate numerical analytical result.
