摘　　要：预应力张弦梁内支撑对基坑周边环境适应性强,具有快速装卸、循环使用、绿色环保等优点,拟采用SAP2000对某基坑的预应力张弦梁内支撑进行分析。经受力分析,该基坑支护的整体受力性能良好。预应力张弦梁内支撑可作为基坑内支撑的有效方式。The prestressed stringed girder internal braces have strong adaptability to the surrounding environment of the foundation pit,and have the advantages of fast loading and unloading,recycling and environmental protection.In this paper,SAP2000 is used to analyze the prestressed stringed girder internal braces of a foundation pit.Through force analysis,the overall mechanical performance of the foundation pit support is good.The internal bracing of prestressed string girder can be used as an effective method for the bracing of foundation pit.

关 键 词：预应力 张弦梁 受力性能
