摘要/Abstract

摘要： 目前国内储罐抗震规范和标准主要基于刚性地基假定,未考虑土体与罐体相互作用以及相邻罐体间的交叉相互作用.基于ABAQUS软件,通过CEL方法建立储罐液固耦合模型,采用三条天然地震波激励,分别对包含单个储罐及多个储罐(储罐群)的土体-罐体相互作用体系进行了地震响应分析.以处于场地中心位置的罐体为研究对象,比较了土体-单罐体系及土体-群罐体系情况下罐体的地震响应.研究结果表明,给定地震输入下,靠近罐体底部0.5 m处罐壁轴向应力均超过临界屈曲应力,罐体发生明显象足变形,周围相邻罐体的存在一定程度上减小了罐体的地震响应.通过对场地地表加速度分析,结果表明罐体的存在会增大地表加速度响应.

Abstract: At present, domestic tank seismic codes and standards are mainly based on the assumption of rigid foundation, neglecting the effects of soil-structure interaction (SSI) and the cross-interaction between adjacent tanks. A coupled liquid-solid model of a storage tank was developed using the CEL method in ABAQUS. Seismic response analyses were performed under excitation from three recorded natural earthquake waves for systems involving both single tanks and multiple tanks (tank groups), incorporating SSI effects. Taking the tank in the center of the site as the research object, the seismic response of the tank in the case of a single tank soil system and a soil group tank system is compared. The research results show that under a given seismic input, the axial stress of the tank wall at 0.5m above the bottom of the tank exceeds the critical buckling stress, and the tank body has obvious elephant foot deformation. The existence of adjacent tanks around reduces the seismic response of the tank body to some extent. Through the analysis of the ground acceleration of the site, the results show that the presence of the tank body will increase the ground acceleration response.
