拖带坐标系下的固结理论及其变分原理

A Consolidation Theory on Co-moving System and Its Variational Principle

本文采用陈至达教授的S-R应变定义建立了拖带坐标系下的三维大变形固结理论,摒弃了经典固结理论中小变形的限制,证明了大变形固结理论的能量率变分原理及其广义变分原理。

A theory of three dimensional finite consolidation is established on co-moving system with Chen's definition of strain, and the limitation of small deformation in classical consolidation theory is given up. The variational principle of energy rate and its generalized one in finite consolidation theory are proved in this paper.
