浅谈仰斜式挡土墙不均匀沉降计算

Brief Discussion on Calculation of Uneven Settlement of Inclined Retaining Wall

摘要:

挡土墙作为支挡结构在公路中的应用较为广泛,科研和水工中经常采用ABAQUS有限元软件对工况简化,运用应力云图等分析挡墙和土体相关参量的变化对工况的影响,公路工程中一般简化工况,采用理正岩土软件进行验算。本文通过手工计算、理正岩土软件、GE05软件对仰斜式挡土墙的稳定性进行分析,给出仰斜式挡土墙偏心距计算的相关建议。

Abstract:

As a retaining structure, the retaining wall is widely used in highways. ABAQUS finite element software is often used in scientific research and hydraulic engineering to simplify the working conditions. The stress nephogram is used to analyze the impact of changes in the relevant parameters of retaining wall and soil on the working conditions. Generally, the working conditions are simplified in highway engineering. The Lizheng Geotechnical Software is used for checking calculation. The stability of the inclined retaining wall is analyzed by the manual calculation, Lizheng Geotechnical Software and GE05 software. The relevant suggestions for calculating the eccentricity of the inclined retaining wall are given.
