抗滑桩与挡土墙协同工作在工程滑坡治理中的应用

The Application of Anti-slide Pile and Retaining Wall Cooperative Work in Landslide Control

随着高速公路、铁路及其它基础设施建设的快速发展,边坡治理不容忽视。抗滑桩相比挡土墙、锚索等工程措施,具有抗滑移能力强,稳定性高等特点,目前已广泛应用于边坡加固工程中。在基岩面下切的场地,将桩位调整,桩前设置挡土墙,不需增加桩长便可有效解决这一问题。采用有限元强度折减法和极限平衡法进行滑坡后边坡的稳定性分析。并采用抗滑桩和抗滑桩+挡土墙的设计方案,为同类工程滑坡的治理提供了经验。

Along with the rapid development of infrastructure construction,such as expressway and railway...etc,slope treatment is indispensable.In comparison to retaining wall,anchor cable,anti-slide pile has features such as higher anti-sliding capability,higher stability,has been widely applied in slope Stabilization.In the site of bedrock surface scour,adjusting pile position,setting retaining wall in front of anti-slide pile,resolve the problem effectively without increasing pile length.Stability analysis by using strength reduction fem and the limit equilibrium method.And using design scheme of anti-slide pile and retaining wall.Provided experience for landslide control of similar projects.
