摘　　要：上海浦东国际机场登机廊采用钢屋架和空间拉索结构体系，群索分４批张拉，通过调整群索张拉力纠正几何偏差；通过计算和比较确定了张拉顺序。施工前采用计算机三维分析技术模拟施工，与实际情况相当吻合，为现代计算机技术应用于建筑施工提供了成功的例证。The passenger corridor of the Shanghai Pudong International Airport has been adopted with a steel roof truss and a space stayed cable structure system. The stayed cable groups have been stretched seperately in four batches.The correction of geometrical deviations bave been done and made by allocation and modification of stretching forces of the group cable. Through calculation and comparison course of stretching procedures could be ascertained. During prior construction there is an analogy construction has been carried out and implemented with tri-vector computer analytical technology. It has proved that the results are consistent with practical condition.And besides,the evidence of application of computer technology bas been proved a perfect success.
