反分析法 - Systemic numerical tests are made first , to study the parameter sensitivity of cohesion and friction angle and other elastic parameters to the convergence in tunnel . some comprehensive parameter sensitivity laws have been draw thought these numerical tests . the method of emulating back analysis is illustrated secondly , in detail by tracing the excavation and supporting conditions by the special numerical modeling rested in final program
主要研究成果： ( 1 )建立使各个参数灵敏度值具有可比性的灵敏度计算公式，不仅得到了灵敏度分布规律，而且还得到了各参数对位移的量化影响结果； ( 2 )详细阐述了岩土工程仿真反演分析思路与具体方法； ( 3 )假定围岩为理想弹塑性模型，在可量测出理论上认为不可测的塑性变形、实现弹塑性位移分离的前提下，提出了弹塑性问题的分步反分析法。 - According to the problem of failure and instability in subgrade engineering , on the basis of inhomogeneous elastic damage model , in this paper fem back - analysis from instability - strength degradation is propose , which suggests that the material parameter obey statistical distribution and it is used to describe the inhomogeneity of material
摘要针对路基工程变形与失稳问题，本文提出了基于非均质弹性损伤模型的有限元失稳强度折减反分析法，认为材料参数服从统计分布，并以此来描述材料的非均匀性。
