This report introduces the principles of mchanized tunneling and provides detailed guidelines for practical application. The subject is introduced with a detailed review of technical aspects and terms relating to mchanized tunneling. It discusses the mechanics of rock cutting and implications on machine performance. Two related issues -- the stability of underground openings and rock mass classification for tunneling -- are presented and serve to fmailiarize the reader with aspects other than rock cutting that affect machine tunneling. All this forms the basis for a comprehensive description of the entire mechanized tunneling system and its operations.
This handbook alerts transportation system planners and designers to planning methods which can lead to more efficient use of earth and rock materials...
This report focuses on improvement of design methodologies related to the ground-structure interaction in tunneling. The design methods range from sim...
