摘要
在主固结阶段,由一维固结理论可推导出沉降速率与沉降之间的线性关系。在次固结阶段,基于Voigt-Kelvin粘弹性模型,也可得到沉降速率与沉降之间的线性关系。根据这种线性关系提出了用于推算地基的固结系数、瞬时沉降量、主固结沉降量和次固结沉降量的方法。最后结合工程实例,说明了该方法的使用。
Based on one dimensional consolidation theory and Voigt-Kelvin viscoelastic model, the performance of ground settlement at primary and secondary consolidation phases is investigated. Analysis results show that the relationship between settlement-velocity and settlement of ground is approximately linear. Based on this linear relationship a method is proposed, which provides an estimation of coefficient of consolidation and of the settlement components including immediate settlement, primary consolidation settlement and secondary consolidation settlement of the ground. An application of the method to a practical case is presented
