指出了我国目前土的本构关系模型研究工作中的一些值得注意的问题,说明了理论模型与曲线拟合的区别;强调了通过试验正确确定模型参数的重要性;分析了建立模型时假设的必要性与合理性;指出了客观、公正的模型验证方法。特别强调了在发展土的本构关系模型中土工试验的重要意义。
Some notable problems in the study of constitutive model of soil in our country are pointed out. The difference between theoretical model and curve fitting is explained. The importance of model parameter is confirmed through experiment. Necessity and rationality; pointed out objective and fair method of model verification. Particular emphasis is given to the importance of geotechnical testing in developing constitutive models of soils.
