重力式挡土墙的设计

Design of the Gravity Retaining Wall

重力式挡土墙是一种用于支撑天然边坡或者人工填土边坡来保持土体稳定的构筑物。重力式挡土墙具有可就地取材、施工便利、经济安全等优点,广泛地用于我国的石油化工、公路、铁路、港湾等工程建设中。挡土墙设计需要同时考虑抗滑移稳定性验算、抗倾覆稳定性验算、地基承载力验算等多个因素,涉及多个公式和参量的计算,通过编制重力式挡土墙计算软件,实现了公式自动计算,简化了设计过程。结合工程实例,研究重力式挡土墙的影响因素及卸荷台的作用。

The gravity retaining wall is a structure which retains a natural slope or an artificial fill slope to maintain the stability of soil. The gravity retaining wall has the advantages of convenient construction, economic and security, and so on. It is widely used in the construction of China＇s petrochemical industry, roads, railways and harbors. In the retaining wall design, the factors of the anti-slip stability, the anti-overturning stability and ground beating capacity should be taken into account; the design involves multiple formulas and calculation parameters. The calculation software of the gravity retaining wall has been programmed to achieve an automatic calculation and simplify the design process. In this paper, combined with the engineering examples, impact factors of the gravity retaining wall and effect of unloading platform were researched.
