摘要

本文介绍了如何为伦敦希思罗机场5号航站楼开发项目建造一系列大直径螺旋钻孔试桩。在永久工程开始之前，对这些桩进行了为期一年的测试，以调查伦敦粘土内的轴阻力如何随时间变化。介绍了试验过程，并给出了一些结果，并进行了简要讨论。另外建造了两个桩来研究伦敦粘土中深度达47米的基础阻力。本文采用奥斯特伯格桩来产生试验力，并对这些桩的施工和试验进行了讨论。

Long-term pile testing in London Clay: a case study

This paper describes how a series of large-diameter auger-bored test piles were constructed for the Terminal Five development at London's Heathrow Airport. The piles were tested over a period of one year, prior to the start of the permanent works, to investigate how the shaft resistance within the London Clay varies with time. The test procedure is described, and some of the results are presented and briefly discussed. A further two piles were constructed to investigate the base resistance in the London Clay at depths of up to 47 m. Osterberg Cells were used to generate the testing force, and the construction and testing of these piles is also discussed in the paper.

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.
