摘要
基于计算基底压力的新方法,通过基底的应力分布特点以及静力平衡条件,得到单向偏心荷载作用下计算基底压力的修正式以及大偏心荷载作用下基底的应力分布图。修正式是完全以有效应原理为核心的一套基底压力计算式,其表达式与土力学现有理论的简化计算式有较大不同,但基底压力的取值和分布范围等定量结果与土力学现有的简化计算式结果相同。
Based on the new method of calculating the base pressure,the stress distribution characteristics and static equilibrium conditions of the base,the modified form for calculating the base pressure under unidirectional eccentric loading and the stress distribution diagram under large eccentric loading are obtained.It is a set of calculation formula for the base pressure with effect principle as the core,its expression is quite different from the simplified calculation formula of the existing theory of soil mechanics,but the value and distribution range of base pressure are the same as the existing simplified calculation formula of soil mechanics.
