摘要

为了评估可用于确定肯特郡一个潜在可塌陷的黄土砖沉积的深度和横向范围的方法，进行了详细的场地特征描述。本文提出的调查包括岩土和地球物理评价，并与现场试验坑的详细岩性测井相关联。这使得锥贯仪剖面可以直接与一套快速地球物理测量技术进行比较，其中包括电磁(EM31和EM34)，电阻率测量和剪切波剖面，针对相同的土壤剖面进行校准。由此可以确定整个试验场湿陷性黄土的可变性和程度，从而证明适当校准的地球物理技术可以提供潜在不稳定土壤深度存在的快速指示。

On-site characterisation of loessic deposits in Kent, UK

A detailed site characterisation was undertaken in order to assess methods that could be used to determine the depth and lateral extent of a potentially collapsible loessic brickearth deposit at a site in Kent. The investigation presented in this paper covers both geotechnical and geophysical evaluations, correlated to detailed lithological logs of trial pits at the site. This enabled cone penetrometer profiles to be compared directly with a suite of rapid geophysical survey techniques, which included electromagnetic (EM31 and EM34), electrical resistivity surveys and shear wave profiles, calibrated against the same soil profile. From this it was possible to determine the variability and extent of a collapsible loessic soil across the entire test site, thus demonstrating that appropriately calibrated geophysical techniques can provide a rapid indication of the presence at depth of a potentially unstable soil.

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.
