• Abstract:
  Recommends improved designs for further research. Emphasis is upon developing procedures to understand and control displacements adjacent to deep excavations. Concepts include both analytical procedures and construction techniques. Suggested methods to improve performance are' (1) Use of stiff walls and pressurized wells in cohesive soil; (2) Prevention of ground loss in "running ground" ; (3) Tiebacks and internal bracing combined in a hybrid support system which will provide superior performance over each system alone; and (4) Earth reinforcement concepts, both horizontal and vertical, designed to diminish the deformability of the retained soil mass. .; Finally, tests sections are proposed to evaluate the concepts advanced In the report.
