摘　　要：钢管混凝土系杆拱桥具有自重轻、承载大、抗变形能力强及施工方便的优点,在我国公路及市政得到越来越广泛的应用。本文以宁波慈城大桥为依托,对该桥施工过程及成桥状态的空间稳定性进行分析,以确保该桥施工过程的安全可靠。With its advantages of lighter self- respect, stronger carrying capacity, better non - deformability and more convenient construction technology, the Concrete Filled Steel Tubular（CFST） arch bridges with arch multi - ribs are applied more and more in the highway projects and the municipal projects in our country. Based on Ci Cheng Bridge in Ning Bo, an space stability analysis which can simulate the construction stages and the dead load state is described here. Finally , the results is shown that the bridge is safe between the construction stages and the dead load state.

关 键 词：系杆拱桥 多肋式 稳定分析
