摘    要:高速公路建设中不可避免地会遇到各种结构类型的斜坡,其稳定性状况在很大程度上决定了工程的投资和工期。因此,研究其工程适宜性具有较大现实意义。从影响路堑边坡稳定性的各种因素出发,应用岩体力学理论和数值模拟技术研究边坡开挖过程中的变形破坏特征,分析地下水、时效特性和工程措施优化等对边坡稳定性的影响,对边坡信息化设计和施工具有一定指导意义。研究表明,路堑边坡岩体的变形破坏特征符合卸荷岩体力学行为,在最优坡度设计基础上,应当及时进行加固。

关 键 词:路堑边坡工程  变形破坏特征  时效特性  动态仿真分析

Abstract:With the development of the highway, the slope engineering is increasingly manifold in many different ways. For the sake of recognizing the characters of excavation engineering rock mass in nature, authors, who are based on the factors influencing theslope, the deformation and destruction characters and discussed, the methods of rock mass mechanical analysis and the numericalsimulation of the slope engineering rock mass are proposed and carrieded. Some results are achieved in research. The characters of deformation and destruction of the slope is not alike that of the regular loading rock action, but according to unloading rock mass mechanics action. The stability analysis of slope rock mass must attach importance to hydraulics and unloading effect, at the same time, some essential measures such as in time reinforcing, avoiding watery process should be considered. It is helpful to promote the information design of the slope engineering.
Keywords:slope engineering  characteristics of deformation and failure  time-effect character  real-time simulation
