Guidelines for Improved Rapid Transit Tunneling Safety and Environmental Impact. Volume II. Environmental Impact.

摘要

Two of the major objectives of the Urban Mass Transportation Administration Tunneling Program are to lower subway construction costs and reduce construction hazards and damage to the environment. This study consists of a two-volume report and aims to develop guidelines for improved rapid transit tunneling safety and environmental impact,that is,this effort is directed toward underground construction applicable to modern transit subway systems in urban areas. Investigation of subway construction jobs shows that at least two principles underlie treatment of environmental problems. First,planning and design should consider both short-term and permanent damage to environment,and second, a need for better communication of contractor's planned activities and public concerns so that disruptions can be minimized. Guidelines were developed along these principles and are grouped into the following categories:general,community relations,and specific environmental control techniques.
