| 摘 要： | 近年随着在软土层上大量建设高层建筑,桩基础被广泛应用,而新的地基处理方法要求对每根桩的质量都须确保,由此一系列经济、快速、可靠的桩检方法应运而生。本文概要地阐述了桩的分类、作用、性能特征和十二种桩检方法,即理论公式法、静荷载法、静力经验公式法、动力公式法、锤击贯入法,机械阻抗法、应力波分析法、水电效应法、球击动测法、基频法、声波及其它测井法、波速动刚度法。指出多种方法综合检测的必要性。

| Abstract: | With the setting up of many tall building on the soft soil layers in recentyears, pile foundations have been extensively applied. The new technique forlaying foundations requires people to guarantee the quality. of every pile and,as a result, a series of economical, rapid and relaible methods for pile founda-tion inspection have been developed. This paper outlines the classification,roles and functions of piles and twelve sorts of pile inspection methodswhich include theoretical formula, static load, static empirical formula, dyna-mic formula, hammer-blow injection, mechanical impedance, stress wave analy-sis, hydroelectric effect, ball-blow dynamic inspection, fundamental frequency,acoustic wave and other logging methods and wave velocity dynamic rigidity.The necessity of integrated utilization of various inspection methods is alsopointed out in this paper. |
