摘要

分析了在考虑地基土体中流体与固体耦合作用情况下加筋土边坡的力学行为

采用Biot固结理论说明了土体中流体与土体耦合作用的机理。通过数值计算比较了在考虑地基土体中流固耦合作用及不考虑流固耦合作用2种情况下

土体的侧向位移、沉降及筋材应变等特点

并与试验路的测试数据相比较。研究结果表明

考虑流固耦合作用的分析与实际情况更吻合。所以

在今后加筋土边坡的力学行为分析中

应尽可能计入流固耦合作用的影响

该研究成果对加筋土边坡的工程实际有一定的指导作用。

Abstract

The mechanic characteristic of reinforced slope is analyzed by considering the coupling between fluid and solid of foundation

and the mechanism of the coupling is illuminated by Biot consolidation theory.Then thevariety of lateral displacements

settlements in the soil and the strain of reinforcement are compared by numerical calculation considering the coupling or not.Outcomes from the calculation are compared with obtained data of a test road.The conclusion is that the outcomes which consider the coupling are more consistent with the real circumstance.So

the coupling between fluid and solid of foundation should be considered as much as possible when analyzing the mechanic characteristic of reinforced slope henceforth.This can be used to guide practical reinforced slope engineering.
