Abstract:

The construction of new rail rapid transit systems and additions to existing systems, has greatly increased the amount of tunneling performed in the United States. Since these transit systems are generally located in urban areas, tunneling is used to minimize the impact of the construction and operation on the community. The objective of this study is to evaluate, through the use of a field demonstration program, the feasibility, applicability, reliability, and cost effectiveness of several advanced methods of subsurface exploration and geotechnical instrumentation to produce data usable for rapid transit tunnel design and construction within the time, cost, and schedule constraints common to the industry. A test section on the Massachusetts Bay Transportation Authority Red Line Extension-Northwest in Cambridge, was selected to evaluate methods of subsurface exploration that investigate geotechnical parameters, and instrumentation used to monitor ground movements due to tunnel construction. Numerous methods of geotechnical instrumentation, including surface and building settlement points, deep settlement points, inclinometers, piezometers, and observation wells, were used to monitor ground movements and groundwater levels within the test section. The performance of the instrumentation methods are evaluated in terms of accuracy, costs, and engineering and construction advantages. In addition, predictions of stratigraphy presented in an earlier report are compared with the stratigraphy observed during tunnel construction. Advanced methods of explorations used for these predictions are evaluated.
