摘要
边坡作为地质体,往往具有复杂的结构和地质力学特征.这些特点在一般的边坡治理工程设计中往往难以全面反映.本文结合实际工程.介绍了在较全面考虑边坡地质体上述特性的前提下.采用数值模拟方法对边坡治理工程所进行的方案论证和设计优化.
It is known that the mechanical benaviours of rock slopes are very compliCated because of its existting environments,variable geological structures and time-dependent effects. So the traditional analysis and design approaches about reinforcement works of slopes based on rigid equilibrium theory are always unsatisfactory to some extent. In this paper, the numerical simulation methods which can describe the complicated geological structures and their mechanical behaviours,such as FEM and DEM ets. are applied to making assessment and verification on the reinforcement plans of rock slopes. It shows that this method is suprior to traditional ones in many aspects.
