Abstract:

The present research project aims at the study of the deteriorations of foundations of concrete dams. Three main steps are envisaged in the development of the work i analysis of case histories on the deterioration of foundations of some Portuguese arch dams and on the behaviour of some Portuguese gravity dam foundations ii study of the hydromechanical behaviour using mathematical and experimental methods and iii studies on the materials and techniques used for the repair works in concrete foundation. Following the approval of the contract last June, Mr. Luis Ribeiro e Sousa, an associate investigator attached to this project, visited the U.S. Army Waterways Experimental Station - WES Vicksburg, USA in the second week of September. The report of this visit is appended Appendix A. Besides the information included in the report of the visit, additional information is included on the planning of the work. The work should be divided into four technical reports, which will be included in the final report. Draft lists of the items to be developed in each report as well as a general plan for the activities are also appended Appendix B.
