层状岩体的弹粘塑性Cosserat介质理论及其工程应用

Elasto-visco plastic Cosserat theory of layered rockmass and its application in engineering

本文以层状岩体为研究对象，建立了考虑弯曲效应的层状岩体弹粘塑性本构关系，推导了有限元计算模式，并将该理论应用于龙滩工程左岸进水口反倾向层状岩体边坡的初始地应力场反演、开挖变形与稳定计算分析中．

In this paper, the elasto-visco plastic constitutive relationship of the layered rockmass is estabished, in consideration of the bending effeCt of rock layers, and the FEM algorithm is deduced. The theory is applied to back analysis of the initial stress field and analysis of the bending deformation in Longtan project. The results are proved to be reasonable.
