摘要

根据粗糙接触面变形机理

建立了基于损伤力学基本原理的接触面本构模型来描述其力学特性。所建议的损伤模型可以用一个统一的表达式来表述

能够较好地反映土与结构物接触面剪切过程中的应变软化和剪胀等力学特性;模型参数较少

物理意义明确。对接触面直剪试验和单剪试验成果进行了验证

模型计算与试验结果吻合较好

表明建议的土与结构物粗糙接触面损伤模型是合理可行的。

Abstract

According to the deformation mechanism of rough interface

a damage model for soil-structure interface was set up to simulate the mechanical characteristics of strain-softening and shear-dilatancy .The model can be expressed by only one formula with clarified physical meaning

and has less parameters .The damage model was verified with the results of direct and simple shear test

and the predicted result by the model is agreeable with test data .It is shown that the proposed damage model is reasonable and practical .
