摘要
在岩土工程中,由于材料的特殊性和施工因素的影响,使得材料参数的确定十分困难,本文通过现场实测位移以二维有限元正分析为基础,应用共轭梯度法对基坑开挖进行参数反分析,并通过实例予以验证。
In geotechnical engineering, the material parameters are difficult to identify as the speciality of the material and the affection of the construction. The theory and application of back analysis by measured displacement were put forward, and the validity was approved by an example.
