我国近些年来以至今后一个相当长的历史时期,都会是国民经济发展的高速阶段。基本建设方兴未艾。隧道及地下工程作为基础设施建设必不可少,其重要性非常突出,甚至无可替代。盾构及掘进机技术在隧道及地下工程建设中发挥的作用日益强势。随着盾构及掘进机技术的不断完善和提高,盾构及掘进机的技术性能越来越好,其应用覆盖面越来越大。总的发展趋势为:原来只能用于软岩和土质的盾构有了一定的硬岩掘进能力;原来只用于硬岩掘进的TBM也具备了在软岩及断层破碎带中的适应能力。盾构、TBM的
In recent years, our country will have a rather long historical period and will be a high-speed stage for the development of the national economy. Capital construction is in the ascendant. Tunnels and underground engineering are indispensable for infrastructure construction and their importance is very prominent or even irreplaceable. Shield and boring machine technology in tunnels and underground construction has played a growing role. With the constant improvement and improvement of shield and boring machine technology, the technical performance of shield and boring machine is getting better and better, and its application coverage is getting bigger and bigger. The general trend of development is that TBM, originally only used for soft rock and soil, has a certain amount of hard rock excavation capability. Formerly used for hard rock tunneling, TBM also has the ability to adapt to soft rock and fault fracture zone . Shield, TBM
