湿陷性黄土地基湿陷变形计算方法的评价

Assessment of calculating methods of collapse deformation of subsoil of collapse loess

对湿陷系数、本构模型和弦线模量等几种计算湿陷变形的方法进行了评价.对比原位浸水和载荷试验结果,湿陷系数计算湿陷变形误差很大,本构模型尚未在工程中推广应用,弦线模量计算湿陷变形最为准确.由于能够准确计算湿陷变形,因而能够按变形控制进行湿陷性黄土地基的设计.

This paper discusses the assessment of calculating methods of collapse deformation of collapse loess subsoil by the coefficient of collapse and constitutive mould and chord mould quantity. In contrast with the home position soaks in water and carry of the lotus to experiment the result, calculation of collapse deformation by coefficient of collapsibility transform the error margin very big, the constitutive mould doesn＇t yet expand the application in the engineering, calculating collapse deformation by the chord mould quantity transform the most accurate.
