灰色GM（1，1）模型在真空预压孔隙水压力分析中应用

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.
