摘要

采用压汞法对天然结构性软土压缩过程孔隙大小分布的演化进行了试验研究，结果表明，当荷载超过结构屈服应力后，尺寸较大的团粒间孔隙首先发生破坏，随着荷载的增大，越来越小的孔隙受到影响，但团粒内孔隙在压缩过程中不发生变化；根据试验结果提出了孔隙结构破损势的概念，并用其表征孔隙分布随荷载变化的规律。

Abstract

Freeze dehydration and mercury intrusion porosimetry was used to study the change of pore size distribution of a structured soft soil

during one-dimension compression. It was found that when pressure increased beyond the structure yield stress

the largest pores began to break down. If the pressure was increased continuously

smaller pores would be affected; but the intra-aggregate pores could not be changed during compression. Pore structure breakage potential was defined in terms of the evolution of the pore size distribution in different stress level.
