堆载预压下软土地基固结研究

Study on Consolidation of Soft Soil Foundation with Surcharge Preloading

摘要:

对塑料排水板堆载预压法作用下的软土地基，采用竖向平均固结度计算公式对分级加载的软土地基的不同时刻的固结度进行推算和预测，并利用实测数据对其检验对比，分析地基土的固结程度，预测地基土达到稳定要求的时间。

Abstract:

For the soft soil foundation under plastic drainage plate surcharge preloading, the consolidation degrees of soft soil foundation with step loading at different time are calculated and predicted by formula of vertical average degree of consolidation, which are compared to the in-situ data to analyze the consolidation degree of the foundation soil and estimate the time required for foundation soil stability.
