舟山国家石油储备基地堆载预压加固效果分析

介绍了舟山国家石油储备基地试验区软基堆载预压大型现场试验结果，根据现场试验测得的数据，分析了软土地基堆载预压下沉降变化规律、分层沉降变化规律、深层土体位移变化规律、超静孔隙水压力变化规律，进一步探讨了根据应力和应变分析得到的地基固结性状，其中通过应变分析得到适用于储备基地的沉降经验系数m。结果表明，打设塑料排水板结合堆载预压处理软弱地基具有良好的效果。

Analysis of consolidation effects of Zhoushan National Oil Reserve Base improved by preloading combined with plastic drains

Firstly, the results of in-situ testing of Zhoushan National Oil Reserve Base improved by preloading combined with plastic drains is introduced. Base on the in-situ measured data, the change rules of settlement, settlement in layers, deep soil displacement, and excess pore water pressure on soft clay foundation under preloading is analyzed; and further study on consolidation effects according to the analysis of stress and strain, including the empirical coefficient m applicable for the base is gained by the strain analysis. Finally, the result shows that the good effect can be gained on the soft clay foundation treated by preloading combined with plastic drains.
