一、前言隧道掘进机是一种高效率的机械化开挖设备。与常用的钻爆法开挖相比,具有洞壁光滑、衬砌量小、安全性高、速度快、连续掘进、一次成洞、可以大大减轻施工人员的劳动强度等优点。因此,从六十年代以来,使用掘进机开挖隧道,已在国内外工程实践中获得广泛地应用。
I. Introduction The tunnel boring machine is a highly efficient mechanized excavation equipment. Compared with the commonly used method of drilling and blasting excavation, it has the advantages of smooth wall, small lining, high safety, high speed, continuous excavation, and one-time hole formation, which can greatly reduce the labor intensity of construction workers. Therefore, since the 1960s, tunnel excavation using tunneling machines has been widely used in engineering practice at home and abroad.
