摘　　要：通过工程实例分析了直梁边桁架、圆弧梁桁架等不同支撑平面布置方案的内力分布特点和各自的优缺点,得到的结论可以用于指导基坑支撑体系的结构优化布置。Several schemes of bracing system were analyzed through case histories.The characteristics of internal forces distribution of these bracing systems as well as their merits and demerits were compared and some useful conclusions were obtained at the same time,which can be used to guide structural optimization of excavation bracing system for other homologous projects.

关 键 词：基坑 支撑体系 内力 变形 优化
