摘要
真空预压法是加固软土地基行之有效的方法,结合工程实例,分析了灰色GM(1,1)模型在真空预压孔隙水压力预测中的可行性,并根据预测结果计算了孔隙水压力固结度,结果表明灰色GM(1,1)模型预测结果准确可信,分析评价结果对工程施工具有重要的指导意义。
Vacuum preloading is an effective technology for consolidating soft foundation. Combining with practical examples, analyze feasibility of GM （ 1,1 ） gray model in prediction of vacuum preloading pore water pressure. Based on result of gray model, calculate consolidation degree with pore water pressure. The results show that prediction of GM （ 1,1 ） gray model is accurate and reliable. Analysis and evaluation results have a good guide to construction of vacuum preloading.
