| 摘 要： | 通过对某机场扩建项目填海及软基处理工程的原位监测情况,利用双曲线法、指数三点法和Asaoka法3种不同方法预测地基最终沉降,并计算平均固结度,分析软基处理效果.同时,基于实测沉降和曾国熙分级加荷法建立简化计算模型,计算地基固结度,并将该固结度计算值与地基平均固结度进行比较,结果表明该方法是合理可行的.

| Abstract: | Through the in-situ observation of marine fill and soft ground treatment of the expansion project of an airport,we forecast the final settlement,calculate the average degree of consolidation,and furthermore analyze the soft ground treatment effect by three different methods,i.e.,the hyperbolic method,the exponent method and the Asaoka method.Meanwhile,we propose a simplified calculation model based on the measured settlement and the stage loading method of Zeng Guoxi,and calculated the degree of consolidati... |
