挡土墙是公路工程中广泛采用的一种构造物,特别在山区公路中,应用更为广泛。公路挡土墙是用来支承路基填土或山坡土体,防止填土或土体变形失稳的一种构造物。在路基工程中,挡土墙可用以稳定路堤和路堑边坡,减少土石方工程量和占地面积,防止水流冲刷路基,并经常用于整治坍方、滑坡等路基病害。主要介绍采用容许应力法进行挡土墙设计的情况,分析公路挡土墙设计中的重点问题,并提出了较为合理可行的建议与措施。
Retaining wall is widely used in highway engineering, a structure, especially in mountainous roads, the application is more widely. Highway retaining wall is used to support subgrade fill or hillside soil, to prevent the deformation of soil or soil instability of a structure. In roadbed engineering, retaining walls can be used to stabilize embankments and cutting slopes, reduce the amount of earth and stone work and land area, prevent the flow of water washed subgrade, and often used to treat landslides and other roadbed diseases. This paper mainly introduces the design of retaining wall using permissible stress method, analyzes the key problems in the design of retaining wall of highway, and puts forward some reasonable suggestions and measures.
