弹性地基梁的计算是一个具有很大实用价值的理论问题。当计算条形基础、片筏基础、地下涵洞、贮液槽及挡土墙等基础结构时都有广泛的用途。一、理想化的地基模型在进行弹性地基梁计算时,研究土体在外荷载作用下的应力应变关系(模型) 即本构方程,是土与基础互相作用问题分析中的一个重要因素。试验研究资料表明,土体的应力应变关系是非线性的。因此要全面地来描述土的应力应变关系特别是应力和应变与时间的关
The calculation of elastic foundation beam is a theoretical problem with great practical value. It has a wide range of uses when calculating basic structures such as strip foundations, ramming foundations, underground culverts, reservoirs, and retaining walls. First, the idealized foundation model In the calculation of the elastic foundation beam, the study of the soil stress-strain relationship (model) is the constitutive equation, which is an important factor in the interaction analysis of the soil and the foundation. The experimental research data show that the stress-strain relationship of soil is nonlinear. Therefore, it is necessary to comprehensively describe the stress-strain relationship of soil, especially the relationship between stress and strain and time.
