Abstract

Excavations for a new service installation in Lindsay Road, Edinburgh, revealed that the ferritic stainless steel reinforcements of the supporting reinforced earth retaining wall were, in parts, severely corroded. This paper presents the findings of an investigation into the cause of the deterioration of the wall. The results of chemical tests undertaken on the backfill indicate that the material was most likely unsuitable for the construction of reinforced earth structures with any of the types of metallic, reinforcement that are, or have been, commonly used. Ferritic stainless steels are now generally considered to be unsuitable for use in reinforced earth structures regardless of backfill type. Indeed, the use of the materials for reinforcements ceased within a few years of the construction of the wall at Lindsay Road. Surveys of the alignments of the wall have also been conducted. The surveys of the wall indicated that there was no measurable movement prior to demolition.

废油页岩充填体中锈蚀不锈钢加固元件的研究
爱丁堡林赛路(Lindsay Road)一处新服务设施的挖掘发现,支撑加筋土挡土墙的铁素体不锈钢加固部分已经严重腐蚀。这篇文章介绍了对墙退化原因的调查结果。对回填土进行的化学试验结果表明,这种材料很可能不适合用目前或过去常用的任何一种金属加固材料建造加筋土结构。铁素体不锈钢目前普遍认为不适合用于加筋土结构,无论回填类型如何。事实上,在林赛路修建城墙的几年内,这些材料的使用就停止了。对城墙的排列也进行了调查。对这堵墙的调查表明,在拆除之前没有可测量的移动。

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.
