工程边坡附加荷载土压力计算研究

Study on the Additional Load Soil Pressure Calculation of Engineering Slopes

工程边坡坡顶附加荷载土压力计算是开展支护结构设计工作的基础,目前建筑类规范对一些特定形式的坡顶附加荷载土压力给出了计算方法,但对于任意附加荷载土压力仍缺少相应计算方法。鉴于此,以现有基坑边坡和建筑边坡规范涉及的计算方法为基础,提出了平面应变下可用于计算任意形式附加荷载土压力的计算方法,为岩土设计人员提供参考。

The calculation of additional load soil pressure on the top of engineering slopes is the basis for conducting the design of support structures.Currently,building codes have provided calculation methods for specific forms of additional soil pressure on slope crests.However,corresponding calculation methods are still lacking for arbitrary additional soil pressures.In view of this,based on the calculation methods involved in existing regulations for excavation slopes and building slopes,a calculation method that can be used to calculate soil pressure for arbitrary forms under plane strain has been proposed.This provides a reference for geotechnical designers.
