摘要
根据北京地区工程地质和水文条件 ,以及北京市地铁施工的特点 ,提出适用于北京地区地铁隧道施工用的盾构机型和盾构机基本配置的技术要求 ,同时还就盾构机扭矩、刀具形状与布置及作用等技术关键点进行了讨论。此外还提出 ,施工企业、国内重工业企业及科研单位三者联合起来共同攻关 。
According to the engineering geology , hydrology condition and construction features of Beijing metro, specifications for machine type and basic accessories applicable for Beijing metro are put forward. The key technical parameters such as shield machine torque, cutter shape and arrangement of cutters, and also their functions are discussed. Additionally, it is suggested that engineering enterprises, domestic heavy industry companies and research institutes may cooperate with each other to design and manufacture shield machines meeting the requirements of Beijing metro.
