海积饱和软土地基处理优化设计分析

针对海积饱和软土地基处理实际工程中采用搅拌桩复合地基和堆载预压排水固结两种方法，进行技术与经济的优化设计分析，预测饱和软土固结度及其沉降特征。通过工程现场监测数据和实际应用效果进行对比，验证理论分析成果和固结度计算以及沉降预测的有效性，结果表明，堆载预压和排水系统的有效结合，对处理沿海饱和软土地基具有良好效果，且经济有效。

Optimization analysis of foundation treatment scheme design in marine

Comparison between two approaches of foundation treatment in the area of marine satur- ated soft soil-cement-mixing pile composite foundation and stacked preloading combined with consol- idation with draining plates was made. Technical and economic optimization analyses were per- formed. Parameters and effect of construction like consolidation degree and settlement features were predicted. By the comparison between site monitoring data and actual application effect, the calcula- tion results of theoretical analysis and consolidation degree and the effectiveness of settlement predic- tion were verified. The results indicate that stacked preloading combined with plastic drain plate can enhance consolidation of coastal marine saturated soft soil.
