Soil Disturbance Due to Installation of Model Piles and Pile Groups
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.
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.
