摘要在施工中，所谓的盾构法就是使用盾构在地面以下开挖隧道的一种方法。随着时间的推移，到了上世纪末，伴随着我国的城市在地下空间的开发和利用率的提高与城市化进程的加快，盾构法作为一种既可以提高施工质量，又可以保护环境的施工方式，得到了政府和施工企业的大力推广和重视，所以，他们渐渐地开始大量的应用与引进这种先进的施工设备与技术。作为对盾构掘进效率和盾构掘进速度有着重要影响的盾构刀具，对于它的质量和选择就尤为重要。在国内，目前我们的盾构使用的刀具绝大部分依靠进口，这是因为第一，盾构在国内而言，是一种新型的设备，没有使刀具的研究人员和制造厂商所重视；第二，国内现有的一些道具不能够满足使用的要求。此文就主要对盾构刀具进行详细的介绍，希望能引起我国一些研究人员和有能力的刀具制造厂商的关注，使盾构刀具的国产化进一步加快。关键词：盾构；刀具；材料；发展趋势AbstractIn construction, a method of shield method is called using the shield excavation tunnel in the below ground. With the passage of time, to the end of the last century, with the development of underground space in our city and improve utilization rate of city and urbanization, the shield as a can improve the construction quality, construction methods and can Protect environment, the government and the construction enterprise promotion and attention, so, they gradually began with the introduction of a large number of applications of this advanced construction equipment and technology. As for shield tunneling efficiency and shield tunneling rate has important influence of shield cutter, is particularly important for its quality and choice. In China, the tool currently using our shield, the vast majority rely on imports, this is because the first, shield in the domestic, is a kind of new equipment, not the tool for researchers and manufacturers attention; second, some of the props of domestic existing can not meet the use requirements. This paper is mainly on ...
