Construction Monitoring of Soft Ground Tunnels: A Rational Handbook of Practices for Rapid Transit System Planners and Managers.

摘要

This report aims to fit the objectives of the Urban Mass Transportation Administration (UMTA) Tunneling Program -to lower subway construction costs and to reduce construction hazards and damage to the environment. This report generated from an UMTA sponsored study that disclosed the art of instrumentation and monitoring as being advanced but not as potentially sufficient on tunneling projects. One of the main reasons for this stemmed from a lack of general procedures and guidelines,as well as, a lack of expertise among decision-makers regarding tunnel monitoring. UMTA commissioned this Handbook to remove such difficulties. The principal purpose of this Handbook is to encourage and improve the use of monitoring for urban mass transit tunnels,and other deep excavations. This Handbook documents the findings of a recent UMTA construction monitoring instrumentation research project. The Handbook is directed to systems planners and managers and points out how to incorporate a successful monitoring program(s) into their systems that help to control and reduce costs.
