英文摘要 | The Orichid-Lake Dam and Reservoir appear to be in a sound, stable conditions after more than 37 years of operation, 9 years of heightening of dam and 5 years of rehabilitation of earthquake damages, and are judged to be capable of safe operation under moderate earthquakes. The behavior under strong earthquakes is more problematic, and a firm assessment will require analysis the total situation including both the main dam, auxiliary dams and poor ridges. The poor ridges near the Chiayi Institute of Agriculture have a history of cracks and shallow slipouts. It is likely that substantial leakage due to heightening of the normal reservoir water level would occur and depend on the capability of the pressure relief well and the drainage system of function. This could influence the stability of the dam embankments as well as reservoir ridges. Critical areas should be identified and data concerning the phreatic water level, pore pressures and engineering properties observed or obtained. The small capacity of the Orchid-Lake suggests that a detailed dynamic analysis may nto a be justified, but a limited instrumentation program may to highly desirable. Also, an inundation map is important. An evacuation program under emergency condition for students of the Chiayi Institute of Agriculture is also recommended. Rapid drawdown procedures should be developed. The necessary evacuation release flow rates and methods, as well as the downstream consequences of these releases, should be identified. The Orchid-Lake Reseroir should be regarded in planning, maintenance. And operational procedures as a critically located lifeline facility for water supply and classified as a “unsafe, non-emergency dam with high hazard potential category” at times of earthquake or other disastrous emergencies. |
