高填路堤重力式挡墙实例分析

Case Analysis about Gravity Retaining Wall below High Fill Embankment

重力式挡土墙因其在稳定路基、节约土地方面的作用被广泛应用于山区高速公路。设计此类挡土墙,除了计算主动土压力和底板配筋,对挡土墙稳定性和地基承载力进行验算,还要注意挡土墙型式、土压力计算重点、墙面坡度与地面坡度的关系、裂缝处理、排水等方面的问题。

The gravity retaining wall is widely used in the construction of mountainous expressway for its advantages in the aspects of stabilizing roadbed and saving land.To design this kind of retaining wall,besides the calculation of positive earth pressure and bottom reinforcement,the checking calculation of the stability of the retaining wall and the bearing capacity of the roadbed,needs to pay attention of the aspects as type,critical calculating points of earth pressure,relationship between wall slope and earth slope,crack treatment and drainage.
