Abstract

The current emphasis on locating building developments on brownfield sites, many of which contain substantial depths of fill, means that the behaviour of fills which support the foundations of buildings is of increasing importance. This paper is concerned with the one-dimensional compression behaviour of these foundation fills. Shallow foundations normally rest on partially saturated ground where the major hazard is associated with settlement due to effects other than structural loading. Consequently consideration is given not only to compression induced by an increase in applied stress, but also to compression consequent on an increase in compressibility associated with an increase in moisture content. A programme of laboratory oedometer tests has been carried out on colliery spoil, an opencast mining mudstone backfill, and a boulder clay fill. The test results have given an improved understanding of fill behaviour in one-dimensional compression and, in particular, the effects of partial saturation on th...

地基填料压缩性
目前的重点是在棕地选址建筑开发项目,其中许多都包含大量的填充物深度,这意味着支撑建筑物基础的填充物的行为越来越重要。本文研究了这些地基填料的一维压缩特性。浅基础通常建立在部分饱和的地基上,在那里主要的危险与沉降有关,而不是结构荷载的影响。因此,不仅要考虑由施加应力的增加引起的压缩,而且还要考虑与含水量增加有关的压缩性增加所引起的压缩。对煤矿矸石、露天采矿泥岩充填体和圆石粘土充填体进行了室内测径仪试验。试验结果提高了人们对一维压缩中填充特性的理解,特别是部分饱和对填充特性的影响。

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.
