Abstract
Based on the engineering practice of an underground integrated pipe corridor,the paper analyzes the cost of urban underground inte-grated pipe corridor before and after the optimization of construction method.The results show that the proportion of civil engineering cost of all building structures before optimizing construction method is more than 80%.In each project of urban underground integrated pipe corridor,the length engineering cost is ranked as shield pipe corridor B>4-cabin pipe corridor>Shield pipe corridor A>3-cabin pipe corridor>2-cabin pipe corridor;Compared with before optimization,the total project cost after optimization is reduced by 5.2%.The largest contribution to the total cost reduction is the shield pipeline corridor B project,accounting for 8.1%;The smallest contribution to the total cost reduction was the three-compartment pipe gallery,which accounted for 5.7%.关键词
