车辆荷载作用下重力式挡土墙设计与验算

Design and checking calculation of gravity retaining wall under vehicle load

针对公路路基挡土墙,考虑车辆荷载,进行挡土墙设计及验算,挡土墙土压力运用库仑土压力理论进行计算,车辆荷载简化为静力荷载,并换算为等代均布土层厚度参与到土压力计算中,设计的挡土墙进行抗滑移和抗倾覆稳定性验算,以确保工程的安全稳定性。

Considering vehicle load,the design and checking calculation of highway roadbed retaining wall are carried out.The earth pressure of retaining wall is calculated by using coulomb earth pressure theory.The vehicle load is simplified as static load and converted into isostatic soil thickness to participate in the earth pressure calculation.The anti-slip and anti-overturning stability of the designed retaining wall is checked to ensure the safety and stability of the project.
