摘　　要：为研究钢-混凝土组合体系的可靠性,文中以昆山阳澄湖科技园项目为例,对大跨度鱼腹梁钢支撑与混凝土支撑组合方案和全混凝土支撑方案进行比选。通过整体建模和监测数据分析,论证了鱼腹梁钢支撑与混凝土支撑组合形式对控制基坑变形的效果更优。说明在工程实践中,鱼腹梁钢支撑与混凝土支撑组合形式性能可靠。This paper studies the reliability of steel-concrete composite system through a practical project in Kunshan,in which the composite scheme of long span steel support of fish-bellied beams and concrete support and the whole concrete support scheme are compared.By integral modeling and monitoring data analyzing,it is proved that the combined form of steel support of fish bellied beams and concrete support is more effective in controlling the deformation of foundation pit.It shows that the combined form of steel support of fish-belly beams and concrete support is reliable and has broad application prospect in engineering practice.
