渐增荷载作用下的土层动态变化特征

Features of Dynamic Changes of Soil Layer under Increasing loading

本文阐明了在逐渐增大的荷载作用下土层内部固结沉降和超孔隙水压力的动态变化特征,以及利用前期现场动态观测资料分析预测土层动态变化的方法。同时结合工程实例分析了理论预测值和实际观测值的差异性,提出了现场动态观测的必要性。

Features of dynamic changes of internal consolidating settlement and over pore water pressure of soil layer under increasing loading and also the method to analyze and to predict the dynamic change of soil layer by using observational data of the dynamic situation on site at the early stage are expounded in this paper. The difference between the theoretically predicted value and the actually measured value is analyzed by engineering case. The necessity of dynamic observation on site is raised.
