Numerical Simulation Research on the Hoisting Process of Reinforcement Cage in Ultra-Deep Diaphragm Wall

Abstract

以上海轨道交通市域线机场联络线工程(西段)梅富路工作井为依托，利用商业软件ABAQUS建立了43 m长的大尺寸钢筋笼的三维数值模型，并根据已有吊装方案分析了大尺寸钢筋笼在吊装过程中分别处于0˚、30˚、45˚、60˚时的变形大小，获得了吊装过程的薄弱位置，并给出了优化方案，为后续大尺寸钢筋笼吊装施工提供参考，可避免安全事故的发生。 Relying on the project of Meifu Road working well in Shanghai Municipal Airport Link (West Section), the commercial software ABAQUS was used to establish a 43 m-long three-dimensional numerical model of the large-size reinforcement cage, and analyzed the deformation of the reinforcement cage according to the lifting scheme when it is at 0˚, 30˚, 45˚, 60˚ during the hoisting process, the weak position of the hoisting process is given by numerical calculation and the optimization plan is given to provide a reference for subsequent large-size reinforcement cage hoisting and avoid the occurrence of a safety incident.
