桩顶非自由端低应变动测法应用研究

低应变动测技术由于其简便、快捷、低成本等优点,已成为各种类型桩基的桩身完整性检测的一个重要手段。大量桩基建筑物在长期使用过程中,特别在外力作用下产生受损,如何对已建结构物下的桩基完整性进行检测越来越引起工程界的重视。近年来通过大量的工程实践,特别是在港口工程的高桩码头完工以后的桩基完整性检测研究,积累了一定的数据资料和实践经验,在此供大家交流讨论。

APPLICATION OF LOW STRAIN INTEGRITY TESTING IN RESTRAIN END OF PILE

Low Strain Integrity Testing is one of the most important technique to pile integrity detecting.But there are still some kinds of piles whose structure and construction have been built upon them,such as piles in wharf,pier and port engineering.How to use Low Strain Integrity Testing method to detect these piles is catching engineers' attention.In recent years,we have collected a great deal of data and accumulated experiences with enough engineering practice,which will be discussed in this paper.
