【摘要】 介绍振动砂箱的构造及工作原理。采用大土样试件模拟实际现场土体的地震作用，专门设计试制了静力触探孔压探头，试图以静力触探法探测试验上在探头贯入过程中的孔压变化，以此推断土的密实状态，为液化的判别提供依据。更多还原

【Abstract】 This article introduces the structure and working principle of the vibrating sand box. The earthquake effect of spot soil is simulated with test specimen. Furthermore. the piezometer tip with static cone sounding is designed for detecting the central pressure change of the test soil during the process of penetration sounding: on that basis. the density of the test soil can be deduced. providing a criterion to judge liquefaction更多还原
