Abstract:

Port Allen Lock is a reinforced concrete U-frame structure located on the west bank of the Mississippi River near Baton Rouge, La. The lock chamber was designed for a trapezoidal distribution of base pressure. This distribution was determined by a trial method in which the plastic and elastic deformation of the base slab and the corresponding deformation of soil foundation were computed for various assumed base pressure distributions until the desired agreement between structure and soil deformations was obtained. The lock chamber was instrumented to obtain engineering data for use in design of similar structures and to determine the validity of the design assumptions. Measurements were made of earth and hydrostatic pressures beneath the base slab and along the walls of the lock and of stresses and strains within the base slab and walls of the lock. The settlement of the lock was determined at various locations, and deflections of the walls were determined by means of wall deflection pipes and a deflectometer. Author
