TESTING OF STEEL SHEET PILE CELLS. INSTRUMENTATION FEASIBILITY STUDY,
Abstract
Devices to measure strains in flat web steel sheet piling, total pressures in soil, hydrostatic pressures in soil, and tilt of a steel piling circular cell, were installed and tested in a full scale active cofferdam cell during its construction to investigate feasibility of placement and continued operation of such instrumentation prior to a design study. The strain and tilt devices performed satisfactorily, but the electrical pressure devices failed. The pressure devices were modified and tested in the laboratory and performed satisfactorily under simulated field conditions. Strains measured in the field project unexpectedly showed severe magnitudes of strains in the webs of the steel sheet piling. Computations of such stresses and laboratory model tests confirmed these field findings. Recommendations are made to perform full-scale tests of a circular steel piling cell for design analysis purposes, using a specially constructed steel sheet piling circular cell and the tested instrumentation. This cell is recommended to be built inside an existing concretewalled enclosure wherein control of structure loading and other advantages may be utilized. (Author)
