江苏镇江蛋山生态治理人工堆山工程地基沉降分析

An analysis of the foundation settlement in the large artificial mountain of the Danshan ecological control of Zhenjiang in Jiangsu

堆山工程是为了有效处理固体废弃物,进行生态城市建设中一种新的工程类型,人工山体地基沉降量是评价其稳定性非常重要的指标。本文采用固结理论与分层总和法分别计算出人工山体地基堆载竣工时与最终的沉降量,并对关键位置地基土体的固结度特征进行了分析,得到了沉降变形、固结度随时间的变化规律。将实测结果与计算结果进行了对比分析,二者基本一致,表明采用这一理论方法可以有效预测人工堆山体地基沉降。

Pile mountain engineering is a new type of engineering in an eco- city construction,which is used for dealing with the solid waste. The foundation settlement of artificial mountain is an important index of the foundation stability evaluation. The settlement and consolidation characteristics of the foundation of an artificial mountain are analyzed in this papor. The settlement at the time of completion and the final settlement are calculated with the consolidation theory method and the layerwise summation method respectively. The relationship among the settlement,degree of consolidation and the time are obtained. The results show that the settlement of theoretical prediction is almost consistent with the actual settlemeut, indicating that the theoretical method can be applied for the prediction of the foundation settlement of the artificial mountain. This study can also provide important reference for similar projects.
