The Expanding Role of Trench less Technology in Underground Construction

摘要

This paper summarizes the types of changes in underground construction and repair expected in the coming decades and how trenchless technologies can be further developed and integrated into the planning, design and management of underground facilities. The historically erratic advances in underground construction technology are reviewed and compared to the rapid current developments in trenchless techniques. Future application opportunities and problems are identified both within the underground utility system arena and as special techniques within a broad variety of underground works.
