某船舶修理厂,围滩填砂造地作为建厂场地,吹填砂面积约为70万米。,吹填砂厚度3～7米。为丫从速决定对吹填砂震动液化的估计和处理方案,进行了调查研究。 一、饱和砂土振动液化的含义及危害 疏松饱和砂士受到振动作用(如地震),短时间内砂土孔隙水来不及排出,孔隙水压力很快上升致使砂土颗粒脱离接触,而处于离散悬浮状态(即 A ship repair shop, enclave beach sand as a construction site, filling sand area of ​​about 700000 meters. , Blowing sand thickness of 3 to 7 meters. Ya for speedy decision on the sand filling liquefaction of liquefaction assessment and treatment programs were investigated. First, the saturated sand vibrating liquefied meaning and harm Loose and saturated sand people are subject to vibration (such as earthquakes), a short time the sand pore water was too late to discharge, pore water pressure rose rapidly resulting in sand particles from contact, and in discrete suspension State (ie
