摘　　要：通过对厦门市曲线斜腿连续刚构预应力系杆拱组合桥施工过程三维模拟分析 ,掌握了这种桥型的受力特点 ,对原设计提出了若干改进意见 ,避免了该桥可能出现的隐患 .对同类工程具有参考价值 .Through the emulational analysis of the construction of the Combination Bridge with curved continuous rigid frame structure and tied-arch bridge, the characteristics of the bridge under the force were grasped. And based on the analysis, some amelioration advices were put forward to the design, therefore the hidden trouble that can be likely to occur in the construction stage was obviated. The analysis also has the reference value for the similar engineering.
