摘要
根据某电厂真空-堆载联合预压地基处理工程中实际监测的孔隙水压力,推算出土体的固结度;再根据静力触探检测的地基承载力结果和钻孔取土的三轴试验数据计算,验证了该固结度计算的准确性。提出了固结度沿地基土深度方向的变化规律与孔隙水压力消散程度的关系,建议固结度采用沿深度方向加权计算的方法,以更确切地反映土体的固结度。
Based on pore water pressure actually monitored during the settlement of vacuum combined surcharge preloading against foundation soil,consolidation degree of soil body can be calculated;then according to the result of foundation soil bearing capacity examined by static probing and the triaxial test data,the accuracy of consolidation degree can be tested.This paper explains the relationship between changes of consolidation degree with depth of foundation soil and dissipation degree of pore water pressure.It is suggested that if the method of weighting is adopted when calculating consolidation degree,which can be represented more accurately.
