摘要
盾构法施工作为一种新型隧道工法,因其先进的施工工艺和不断完善的施工技术,使得其在城市地下空间的开发中取得了巨大的成功,并被越来越多地应用于城市地铁、越江通道以及地下管线等隧道工程的建设中。与此同时,由于其高昂的造价,使得这种工法的进一步推广受到限制。文章在分析了国内外众多工程实例的基础上,研究了盾构法隧道的成本构成,并结合现有的技术水平,从管片和衬砌、盾构机器设备、竖井建造和高速化施工等四个主要方面论述了如何进行成本缩减,从而达到降低工程造价、更好地指导设计与施工的目的。
Shield tunnel method has great success in the development and utilization of underground space. Because of its advanced and continually improving engineering techniques, shield tunnel machines are being widely used in the constructions of metro lines, channel tunnels and underground pipelines. In the meantime, by reason of high cost, this technique is confined for further application. Based on the analysis of plentiful engineering examples at home and abroad, the cost composition of shield tunnel is studied. According to current technique level, the cost cutting is discussed in the following four main aspects: segment and lining, shield tunnel machine, pit fabrication, and high speed construction, consequently, the aim of cutting engineering cost and directing design and construction can be achieved.
