堆载引起某厂房坍塌事故的初步分析 English Version

摘要: 通过对超载作用下地基软土性状的研究 ,指出由长期堆载甚至超载引起邻近桩基较大的侧向位移和位移累积是上海某工业厂房屋顶坍塌的主要原因。文中采用改进弹性地基梁法对堆载邻近的桩基进行理论分析 ,并通过桩基沉降和侧向位移对桥梁等上部结构影响的统计分析 ,提出了堆载大小和桩基变位的控制标准

Abstract: Based on the research of soft soils under overloading, this paper draws a conclusion that lateral displacement of pile foundation caused by soil movement due to surcharge load is the main cause for the collapse of an industrial building. A modified elastic foundation beam method is herein employed to study the single pile adjacent to the surcharge load. Furthermore, by statistically investigating the effect of settlement and lateral displacement of pile foundation on bridge abutments etc.,the control criteria of surcharge load and lateral displacement for pile foundation subjected to soil movement are proposed.
