市政道路上硬下软反倾边坡变形破坏及稳定性分析OA

In order to effectively explore the failure mechanism of the upper hard and lower soft anti-dip slope,this paper takes the treatment of the anti-dip slope of YK17+500-YK17+700 section of the municipal road reconstruction and expansion project of Gaofeng sewage Treatment Plant in GUI'an New Area as an example,systematically analyzes the deformation and failure characteristics and mechanism of the upper hard and lower soft anti-dip slope,and calculates and evaluates the stability of the slope by establishing a numerical model.The results show that slope excavation and rainwater infiltration provide conditions for landslide formation.The stability of the slope does not meet the standard re-quirements under the conditions of the current state and excavation to the design elevation,so it is necessary to implement reinforcement treat-ment and fully consider the possibility of deep slip in the future.
