摘　　要：结合高层建筑跨越地铁实际工程,运用SAFE软件计算厚板转换层的内力,介绍了厚板转换结构计算模型的选取、荷载施加的方法、内力分布的规律以及控制厚板变形和减少温度应力的措施,包括分层叠合浇筑如何考虑,以及设置柔性垫层等措施。Combined the design practice of the tall buildings crossing metro tunnels,used the SAFE software to calculate the internal forces of the thick plate of transition,introduced the selection of computational model of the thick plate of transition,the methods of load applied,distribution regularity of the internal force,controlled the deformation of the thick plate and measures to reduce temperature stress, included the measures of how to consider stratification superposition-method construction and set up the flexible cushion.
