ABSTRACT:
The invention relates to construction of subways or the like using precast, prestressed, ribbed arch concrete panels to build subways with or without utility chambers and above or below ground water. One approach constructs a subway without utility chamber substantially entirely through the use of the concrete panels while the other constructs a subway with utility chamber utilizing poured concrete walls for the utility chamber with the procedure being adapted to a cut and cover method for minimal influence on traffic flow and the train tunnel being formed of the concrete panels.
