摘要
介绍在广州新客站大型钢结构吊装施工方案制定时,通过模拟计算及研究,解决了在采用"半逆作法"的吊装方案中,高架层混凝土楼板预应力张拉对钢结构的应力叠加相互影响的关键技术。
This paper introduces when Guangzhou Passenger Station developed the planning of the large steel erection construction program,it has solved the key technology of the superposition interaction because of superimposed stresses to steel structure by the elevated concrete floor's pre-stressed tension in using 'semi-reverse' for the lifting scheme through simulation and research.
