物探方法与基桩质量检测

GEOPHYSICAL PROSPECTING METHOD AND CHECK OFFOUNDATION PILE QUALITY

近几年来,基桩质量无损检测技术发展较快,特别是物探工作者从事此项工作后,不仅开拓了物探新的应用领域,同时也给桩检技术带来了新的生机。本文综述某些物探方法及其变种在基桩质量检测方面应用现状、取得的成绩及存在的问题;介绍几种可能会有潜力但尚未开展的方法;最后,对这项工作今后发展方向谈几点不甚成熟的意见。

Abstract In recent years, the non-destructive check technique for quality of foun dation pile has developed rapidly. The geophysical prospecting workers' parti cipation in this work, in particular, has not only opened up a new appli cation field for geophysical prospecting, but also brought new vitality for the pile- check technique. This paper summarizes the application of some geophysi cal prospecting methods to the check of foundation pile quality; their pre sent application situation, the achievements gained and the existent troubles. It also recommends some techniques which show latent potentiality but have not yet been employed. Finally, it advances some tentative opinions concern ing the future development of this method.
