一、土的本构方程土的本构方程(本构一词英语为Constitutive我国土力学界于70年代才开始使用)亦有人称之为土的应力应变数学模型。 1978年在武汉召开的力学规划岩体力学分支学科工作会议提出,土的静、动态本构关系是“研究土体在受力状态下,土体内应力、应变、应变率、应力水平、应力历史、加载率、加载路径以及时间与温度等之间的函数关系”。我们认为,假若将成因及历史赋与土的工程特性这点考虑进去,这个阐述就更全面了。
1. Soil constitutive equations The constitutive equations of soil (Constitutive English is Constitutive’s use in the soil mechanics circles in the 1970s) Some people also call it the soil stress and strain mathematical model. In 1978, the sub-discipline of mechanics planning for rock mechanics held in Wuhan proposed that the static and dynamic constitutive relation of soil is “research on the stress, strain, strain rate, stress level, stress history of soil under stress. , load rate, load path, and functional relationship between time and temperature." We believe that this interpretation will be more comprehensive if we take into account the causes and history and the engineering characteristics of the soil.
