HISTORY OF LOADS AND DISPLACEMENTS FOR A DEEP EXCAVATION IN A MIXED SOIL PROFILE

A history of the behavior of an 82-ft-deep excavation for the Washington, D.C. subway is presented. Improvements in the methods for limiting and forecasting soil movements should result in reduced construction costs and damage claims. It was found that the largest volume of soil displacement takes place beneath the advancing excavation and accounts for approximately 60 percent of the total lateral displacement. Maximum apparent earth pressure for this excavation can be predicted by a trapezoidal earth pressure envelope of width 0.25 gamma H (where gamma is the soil unit weight of 120 pcf and H is the full depth of excavation).
