Field Tests of the Cucaracha Formation, Panama Canal 1942-1946.
Abstract
This report describes and presents the results of field studies of shales of the Cucaracha formation conducted during 1942-1946 by the Special Engineering Divison of The Panama Canal Company in connection with the design of the Third Locks Project. Geology of the area in the vicinity of the then-proposed New Pedro Miguel Lock where the field studies were made, as presented in this report, was based on a review of geological studies available at the time of the tests supplemented by more recent studies and exploration of the Cucaracha formation by geologists of The Panama Canal Company and the U. S. Army Engineer Waterways Experiment Station. Measurements were made of structure settlements, settlements adjacent to the structure up to 40 ft away, and pressures immediately beneath the base of the structure. Recommendations made by a board of consultant in February 1945 following review of the test results are included in this report. The data indicate that settlement of large structures on Cucaracha clay shales could be higher than anticipated in 1945. It is recommended that analyses be made of the test data using present-day analytical methods.
