摘　　要：本文根据原位测试资料和大面积试坑(直径40m)浸水试验的实测数据,对黄土与古土壤交互层地基的自重湿陷量计算值与实测值作出比较。探讨了自重湿陷的时间历程,湿陷量沿深度的变化规律以及湿陷的影响范围。通过试验与分析,最后对该类地基土湿陷性作出了评价。According to observed data from in-situ test and immersion of large pit test, the calculated and observed values of self-weight collapsibility were compared for subsoil with interbedded strata of loess and fossil soil. The time-varying, depth-varying and influence zone of self-weight collapsibility were discussed. Assessment from experiment and analysis of subsoil collapsibility was made.
