关于流土和管涌的试验研究和理论分析

The Experiments Study and Theoretical Analyses on Piping and Flowsoil

该文从机理的角度对流土和和管涌破坏的概念、试验研究、有限元分析和解析分析等作了较为系统全面的研究。关于流土和管涌的形成机制 ,突破现有研究成果仅局限于宏观定性认识 ,进行对比性研究 ,定量分析 ,考虑潜在的流土通道的形成过程及流土通道形成后对地下水渗流的影响 ;模拟流土从发生到破坏的过程 。

This thesis mainly studies the mechanism of piping and flowsoil in four aspects which include concepts,experiments,finite elements analyses and analytic analyses.As a result,this study has gone beyond the present levels and do the antithetic and quantitative analyses.At the same time,this study takes into account the forming of the flowsoil channel and the effects on the underground water seeping that it brings.So this study can simulate the flowsoil process from the beginning to the ruin.And the experiments data has proved that finite elements model and analytic resolution are practical and perfect.
