超固结状态下裂隙粘土的强度特性

The Shearing Strength Behaviours of Overconsolidated Fissure Clays

本文是对典型超固结裂隙粘土强度特性的研究结果。通过分析目前国内外研究现状及存在的问题，作者重点结合阳安线、焦枝线的５种裂隙粘土，研究了超固结状态下土体的强度特性，从而提出了超固结裂隙粘土“原位抗剪强度线”及其凝聚力、内摩擦角的确定方法和相应的计算公式。

The research results for shearing strength behaviours of typically overconsolidatedfissure clays are given in the paper. Five types of such clays located along both Yang-an andJiaozhi railway lines are studied with analysis made on the present situation and existingproblems at home and abroad related to the research sublect.As a result,the in situ shear-ing strength line and the methods and corresponding formulas used to determine and calcu-late the cohesion and internal friction angle for the over-consolidated fissure clays are intro-duced.
