饱和砂土挡墙被动破坏超孔隙水压力试验研究

Experimental investigation on excess water pressure of saturated sand with passive failure behind retaining wall

通过自制饱和砂土挡墙模型箱,对于不同挡墙位移模式和位移大小,测试了不同相对密度饱和砂土挡墙被动破坏过程中超孔隙水压力,揭示了饱和砂土挡墙后砂土破坏机理。对深入研究土与挡墙共同作用具有理论价值,对更加合理设计挡墙、控制稳定具有指导意义。

Excess water pressure of saturated sand for different relative density behind rigid retaining wall with different movement model and displacement is investigated by homemade retaining wall model box, then the deformation and failure mechanism of saturated sand behind re- taining wall is revealed. The results has theoretical values for further research on interaction between soil and retaining wall, and also proves guidance for more reasonable design retaining wall and stabilization control of retaining wall.
