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。
In recent years, as a large number of high-rise buildings have been constructed on soft soil, pile foundations have been widely used, and new foundation treatment methods require that the quality of each pile must be ensured. Therefore, a series of economical, fast, and reliable pile inspection methods should be applied. And students. This paper outlines the classification, role, performance characteristics, and twelve types of pile inspection methods for piles, namely theoretical formula method, static load method, static empirical formula method, dynamic formula method, hammer penetration method, mechanical impedance method, Stress wave analysis method, hydropower effect method, ball-actuation test method, fundamental frequency method, acoustic wave and other well logging methods, wave velocity dynamic stiffness method. Point out the need for comprehensive detection of multiple methods.
