| 摘 要： | 龙江特大桥是保(山)腾(冲)高速的控制性工程,研究桥址区的边坡稳定性至关重要。通过对某碎裂岩质边坡工程地质条件、边坡结构的研究,以岩体中结构面特征的分析为依据,结合GEO5有限元模拟,分析边坡破坏模式、形成机制和稳定性。结果表明边坡目前处于不稳定状态,失稳模式主要是由结构面和软弱夹层控制的岩体失稳。

| Abstract: | Longjiang super bridge is the key engineering in Baoteng highway,so investigating the slope stability of the bridge site is vital.Firstly,this paper studied the geological conditions and slope structure of a cataclastic rock slope engineering.Then,based on the analysis of characteristics of structural plane in rock mass,GEO5 finite element simulation was employed to analyze the failure mode,formation mechanism and stability of the slope.The results show that the slope is at unstable state that is primarily determined by the rock instability controlled by the structural plane and weak interlayer. |
