非线性理论在边坡工程研究中的应用
|
摘要
边坡系统是开放的非线性系统,边坡岩土体的力学性质具有非线性特征,由于各因素间非线性作用、物质和能量交换及其本身的非线性,因此非线性是边坡工程的本质属性.简要介绍了1970年以来发展起来的非线性理论在边坡工程中的应用现状,指出应用中存在的问题:生长点问题、脱离地质基础等,研究有待进一步深入.
The slope system is an opening one with complex structure and function in which all factors interplay,the mechanical parameters of rock and soil masses in the slope are of nonlinearity,as a result,the nonlinearity is the inherent property of slope engineering.The applications of the nonlinear theories developed from 1970 to slope engineering are introduced,and the problems are pointeed out(about) the grouth points,breaking away from the basis of geology,ect.It is pointed out that the study needs to be done further.
