隧道盾构法施工是使用盾构机在控制开挖面及围岩不发生坍塌失稳的同时,进行隧道掘进、出渣,并在机内拼装管片形成衬砌、实施壁后注浆,从而不扰动围岩而修筑隧道的方法。但因其造价高昂,使其进一步推广受到限制。针对隧道盾构法施工成本及降低成本措施两方面进行了探讨。 Tunnel shield construction is the use of shield machine in the control of excavation surface and surrounding rock collapse collapse instability at the same time, tunneling, slag, and assembled in the machine to form lining lining, the implementation of wall grouting, and thus Do not disturb the surrounding rock and the method of building a tunnel. However, due to its high cost, its further promotion is limited. Aiming at the construction cost and cost reduction measures of tunnel shield method, two aspects are discussed.
