Abstract

Relatively little attention has been given in the past to the soil disturbance due to installation of a single pile or pile group.

This paper investigates the soil (Leighton-Buzzard Sand) disturbance due to installation of a single pile and pile groups. The technique which has been previously used at Leeds University (UK) is based on the fact that changes in sand density cause changes in thermal conductivity of the sand.

Model piles which have a diameter of 40 mm and overall length of 1 m each were driven individually by a drop hammer into medium dense and dense air-dried sand.

The effects of the initial sand density, the shape of the pile’s bottom and the spacing between piles on soil disturbance are examined. These factors were found to be very significant and various zones of loosening and compaction of sand were observed in regions below and beside the pile, inside and outside the periphery of the pile group.

模型桩及群桩安装引起的土体扰动

在过去，由于单桩或群桩的安装而引起的土体扰动很少受到重视。本文研究了单桩和群桩安装引起的土壤(莱顿-布扎德沙)扰动。这项技术之前在英国利兹大学(Leeds University)使用过，其原理是沙子密度的变化会导致沙子导热系数的变化。模型桩直径为40mm，总长度为1m，分别用落锤打入中密、密实风干砂中。考察了初始砂密度、桩底形状和桩间距对土体扰动的影响。结果表明，这些影响因素非常显著，在桩下、桩旁、群桩外围内外均存在不同程度的砂土松动和压实区。

期刊介绍： Soils and Foundations is one of the leading journals in the field of soil mechanics and geotechnical engineering. It is the official journal of the Japanese Geotechnical Society (JGS)., The journal publishes a variety of original research paper, technical reports, technical notes, as well as the state-of-the-art reports upon invitation by the Editor, in the fields of soil and rock mechanics, geotechnical engineering, and environmental geotechnics. Since the publication of Volume 1, No.1 issue in June 1960, Soils and Foundations will celebrate the 60th anniversary in the year of 2020. Soils and Foundations welcomes theoretical as well as practical work associated with the aforementioned field(s). Case studies that describe the original and interdisciplinary work applicable to geotechnical engineering are particularly encouraged. Discussions to each of the published articles are also welcomed in order to provide an avenue in which opinions of peers may be fed back or exchanged. In providing latest expertise on a specific topic, one issue out of six per year on average was allocated to include selected papers from the International Symposia which were held in Japan as well as overseas.
