摘要
随着隧道工程施工技术的发展,采用盾构法施工越来越广泛。建设项目所需的盾构管片,是购买还是临时建厂预制,此文结合京沈客运专线望京隧道工程实际,通过建立费用计算模型,计算2种方案所需的综合费用,并进行对比。通过对比分析主要参数的敏感性及管片数量对参数敏感性因素的影响。据此提出控制措施。
With the development of tunnel construction technology, construction by shield method is more and more widely. The shield lining segments needed for the construction project is to buy or prefabricate by tempo- rary factory are discussed. Combined with the Beijing - Shenyang passenger dedicated line Wangjing tun- nel engineering practice, through the establishment of cost calculation model, Comprehensive cost is cal- culated by the 2 kinds of solutions and compared. parameters and the influence of segment number on put forward. Through the contrast analysis of the sensitivity of main parameter sensitivity factors, the control measures are
