摘要
针对南水北调中线总干渠潮河段隧洞工程的水文地质和工程地质条件,结合隧道结构、管片形式和施工特点,从土压平衡盾构和泥水平衡盾构的掘进机理及对不同地层的适应性进行分析。根据2种盾构的工作状况、出渣设备、施工场地、经济性、环境影响等多方面特点,对土压平衡盾构和泥水平衡盾构进行综合比较,提出适用于潮河段隧洞工程施工用的盾构机型。
Regarding the engineering geology, hydrology, structure, segment types and construction features of Chaohe tunnel on Central Route of South-to-north Water Transfer Project in China, analysis is made on EPB shield and slurry shield in terms of working principle, adaptability to different ground types, mucking equipment, site requirement, economic benefit, environmental impact and in the end shield machines suitable for Chaohe tunnel are proposed.
