Geotechnical Problem and Practice of Dam Engineering

A large dam is the most complex and hazardous of all civil engineering structures. Designing and building adam successfully relies more on art than on science. There is still a continuing debate in profession as to the places of precedent, theory and judgement in the design of dams. In the fifth Laurits Bjerrum memorial lecture, Professor Peck asserted that engineering judgement and earth dam-design go hand in hand, and modem dams seldom if ever fail because of incorrect or inadequate analyses, they fail because inadequate judgement is brought to bear on the problems. Professor Peck would like to see that dams are designed and constructed not to fail, even if a probability of failure is incorporated into the benefit-cost analysis. He has warned that the achievement of such an objective does not depend on the acquisition of new knowledge, it depends on our ability to bring the best engineering judgement to bear on problems that are essentially non quantitative, having solutions that are non-numerical. This memorial lecture in honour of the memory of Laurits Bjerrum was delivered on May 5, 1980 and it certainly appears more than appropriate that the International Symposium on Problems and Practice of dam engineering, held at AIT, Bangkok in December of the same year focussed attention on some of the issues raised by Professor Peck. This volume presents contributions made at this symposium. Mr. Pierre Londe, President of the Commission on Large Dams, in his presentation on Lessons from Earth Dam Failures, focussed attention on the fact that failure of a dam is the result of a complex concourse of causes and mechanisms, which should be interpreted with extreme care. Professor Victor F.B. de Mello, currently President of the International Society of Soil Mechanics and Foundation Engineering, made stimulating contributions on Practice, Precedents, Principles, Problems and Prudence in Embankment Dam Engineering; Comparative Behaviour of Similar Compacted Earth-Rock Dams in Basalt Geology in Brazil, and Some Problems and Revisions Regarding Slope Stability Assessment in Embankment Dams. Professor Seed reviewed the state-of-the-art regarding Earthquake-Resistant Design of Dams, and Dr. Sembenelli reviewed the Recent Trends in the Design of Earth-Rock Dams. Dr. Meigh and Dr. Penman presented state-of-the-art reports on Geotechnical Investigations for Dams, and Instrumentation Requirements for Earth and Rockfill Dams respectively. Dr. Marchini and Dr. Idel dealt with foundation treatment aspects, viz; Grouting works in Dam Engineering and Seepage through Jointed Rock-sealing and Drainage Measures for Earthfill and Masonary of Dams respectively. Hunter, Mikuni, Professor Yudhbir, Vail and Eastaff presented critical reviews of the practice of dam engineering under different geologic environments. Topics on environmental considerations, geologic control and case histories of dam construction were discussed by Ludwig, Takahashi, Casinader, Jones and Mass, Kulesza, Soerjono and Fujita. Country reports on problems and practice of dam engineering were presented by Agha, Abesamis, Chu, Soerjono, Hung and Kim for Pakistan, the Philippines, Republic of China, Indonesia, Singapore and West Malaysia, and Korea, respectively. A total of twenty seven contributions are reported in this volume. For ease of reference these contributions are divided into four sections: Section A - Priciples, Problemes and Practice; Section B - Investigations, Instrumentation, and Foundation Treatment; Section C - Environmental considerations, Geologic Control and Case Histories of•Dam Construction; Section D - Country Reports.
