Abstract

In geotechnical engineering, stability of the openings formed by excavation is of much concern in controlling the design feasibility and construction workability of underground structures. Analysis of the stability of the excavated openings and the corresponding measures against instability inevitably necessitate a good understanding of the yielding and failure mechanisms of the openings. This paper proposes a mechanism of potential yielding across an excavated rectangular diaphragm wall panel trench. By using an elastic analytical solution to the problem of horizontal stress changes and displacements induced during the installation of a rectangular diaphragm wall panel, two extreme cases (panel trenches with dimensions 1 m × 1 m and 6 m × 1 m) have been analysed to investigate the distribution of the principal stress change of the soils around the trenches due to excavation. It has been found that, when the elastic limit is reached, soils with different consolidation histories will exhibit different yiel...

矩形沟槽的屈服机制
在岩土工程中,开挖形成的孔洞的稳定性是控制地下结构设计可行性和施工可行性的重要因素。分析开挖孔洞的稳定性及相应的抗失稳措施,必然需要对孔洞的屈服和破坏机制有较好的认识。本文提出了开挖的矩形连续墙板沟槽的潜在屈服机理。采用矩形连续墙板安装过程中引起的水平应力变化和位移问题的弹性解析解,分析了两种极端情况(1 m × 1 m和6 m × 1 m的板沟),探讨了开挖引起的槽周围土体主应力变化的分布。研究发现,当达到弹性极限时,不同固结历史的土表现出不同的屈服特性。

期刊介绍: The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
