双面排水非线性固结超静孔压的非对称性解析
Spatial asymmetry of excess pore pressure during nonlinear consolidation with two-way drainage
摘要
Abstract
Based on fundamentals of continuum mechanics with Eulerian description method and the corresponding configuration transform relationship, a strict functional form on excess pore pressure (EPP) and void ratio during nonlinear consolidation of saturated soil is presented in this paper to study the development of EPP with a general meaning of nonlinearity. According to the analytical solution to linear finite-strain one-dimensional consolidation by Morris and the presented functional form, analytical solutions to EPP occurred with two-way drainage are put forward for normally consolidated and dead weight consolidated soils respectively. Thereafter, the asymmetry characteristics of EPP and the impact factors are investigated through a numerical orthogonal experiment. The results show that a dimensionless parameter N plays a dominant role in the spatial distribution behavior of EPP during nonlinear consolidation. For the case of non-zero N, the symmetry distribution of EPP in context of classic Terzaghi's theory is not suited to nonlinear consolidation.关键词
