| 摘 要： | 超固结土的前期固结压力大于其现有的自重压力(Pc>P0),说明土体在形成的历史中曾经受过比现有自重压力更大的固结应力,超固结土往往具有特殊的工程力学性质。基于福建宁德三都澳地区的超固结土的直剪试验,说明在不同压力下土样直剪抗剪强度的测定方法,分析该指标的适用性。

| Abstract: | In the history of over-consolidation soil formation, more consolidated stress is borne than deadweight, so over-consolidation soil is of special engineering mechanics property. Based on direct shear test of over-consolidation soil in Sanduao area of Ningde in Fujian Province, we summarize the methods to measure direct shear strength of soil sample under pressure, and analyze the applicability of this index, which will provide references for similar project design. |
