近年来,为了检测已埋设的混凝土桩的完整性,要求进行完整性试验(Integrity test)。完整性试验方法是用锤轻击桩头同时测出桩的反应(一般为桩的加速度),以检验桩的埋入长度、桩断面缩小或扩大以及其位置、有无裂缝和产生的部位等桩的完整性的非破损检测方法(如图1所示)。随着近年现场灌注桩的需要,上, In recent years, in order to test the integrity of buried concrete piles, an Integrity test has been required. Integrity test method is to measure the response of the pile (usually the acceleration of the pile) by hammering the pile head at the same time to check the buried length of the pile, the reduction or enlargement of the pile section, the position of the pile, the presence or absence of cracks, and the locations of the piles. Pile non-destructive integrity testing method (as shown in Figure 1). With the need of cast-in-place piles in recent years,
