岩质边坡开挖及支护有限元模拟与分析

Finite Element Simulation and Analysis of Rock Slope Excavation and Support

以岩质边坡为研究对象,结合相关工程资料,对岩质边坡岩体的稳定性以及破坏形式等内容进行了综合分析,并运用ADINA软件建立三维弹塑性有限元模型,对边坡的开挖和加固过程进行动态模拟,系统地研究开挖及支护过程中边坡岩体的变形、应力特征以及边坡的整体稳定性。

This paper takes the rock slope as the research object, combines the related engineering data, carries on the comprehensive analysis to the rock mass stability of the rock slope and the rock slope failure form and so on. ADINA software is used to establish three-dimensional elastoplastic finite element model, and dynamic simulation of slope excavation and reinforcement process is carried out, so as to systematically study the deformation and stress characteristics of the slope rock mass and the overall stability of the slope during the excavation and support process.
