Abstract

Abstract:

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.

Key words: Central Route of South-to-north Water Transfer Project, geological condition, shield type selection
