摘要:
由于传统的地基变形计算方法应用于计算大型基础下层状土变形的局限性,在对国内外非自由场(受载)层状土的变形性能研究现状及其发展趋势进行深入分析的基础上,总结了非自由场层状土的体变理论在工程应用中尚存在的问题。结果表明,目前对层状土的静动力体变特性研究还不够深入,现有方法不能在宏微观两个层面上表征土骨架与孔隙水的相互作用,无法同时考虑地基中不同类型土的本构关系、物理力学性质及基底有效附加应力的空间传递与叠加过程,导致计算结果与实际情形相差甚远,只能靠引入经验系数的做法来解决问题。基于此,选取适用于描述非自由场层状土体变特性的理论方法,揭示土-水-力多场耦合作用下复杂地基土的变形演化规律,构建科学合理的层状土体变预测模型,是今后需要深入研究的方向。
