BEHAVIOR DURING CONSTRUCTION OF THE DUPONT CIRCLE SUBWAY STATION LINING

The paper reports on the results of an instrumentation program conducted during construction of the station in Washington, D.C. The primary objective of this study was to evaluate the short-term performance of the lining for a large, shallow underground opening in rock. Lining behavior was evaluated with respect to induced moment, thrust, and deflection. The instrumentation program was conceived to verify assumptions made in lining design and to provide insight into procedures for designing and constructing thick, permanent shotcrete linings. Among the subjects discussed are rock mass geology at the project site, construction sequence and the instrumentation program, measured behavior of the station and a comparison of the measured behavior with the results of a stress analysis of the lining.
