在比较总应力法、有效应力法、有效应力增量法的静止土侧压力(K0)系数定义差异基础上,简述了影响K0系数的主要影响因素(如物理力学性质、应力历史、土体结构、土样受扰动程度、孔隙水压力、土体固结程度)的研究现状,综述了室内试验、原位测试试验、经验公式、本构模型、数值仿真试验确定K0系数的方法的研究进展,可为未来K0系数的深入研究提供借鉴。
On the basis of comparing the definitions of static soil pressure (K0) coefficient of total stress method, effective stress method and effective stress increment method, the main influencing factors of K0 coefficient (such as physical and mechanical properties, stress history, soil Structure, disturbed degree of soil sample, pore water pressure and soil consolidation degree), the research progress of methods for determining K0 coefficient by indoor test, in situ test, empirical formula, constitutive model and numerical simulation are summarized , Which can provide reference for further research on K0 coefficient in the future.
