The technique of " birth and death element " is applied to the simulation analysis for the construction process of cfst arch bridge , which makes modeling job very simple in orderly - erecting analysis and inversely - erecting analysis , and data transferring very easy between them . what ' s more , the order flows about the simulation analysis is programmed based on ansys software , which makes simulation analysis rule and simple 笔者将“单元生死技术”引入到钢管混凝土拱桥施工过程的模拟分析中，解决了正装分析和倒装分析中繁琐的建模问题和复杂的数据传输难题，并编制出相应的ansys命令流程序，以实现施工仿真分析的程序化、简单化。
