牡丹水庫大壩為一中央心層分區滾壓土石壩，壩頂長445.6公尺，最大壩高約65公尺，壩頂高程EL.145m。溢洪道設於左岸，為明渠洩槽式，右側與大壩銜接，其進口為弧形閘門控制之溢流堰，下接洩槽，尾端設有戽斗及落水池。為確保水庫蓄水之安全與穩定，壩體、溢洪道及鄰近邊坡於施工期間埋設有監測儀器，作為水庫營運期間大壩安全行為觀測，以提供水庫下游民眾生命財產之安全保證。配合監測儀器之觀測對大壩進行定期或不定期安全檢查，以確保本水庫蓄水之安全性。由於土石壩安全監測研判分析工作涉及土木、大地、水利、地質、儀器系統等多項專長的結合，屬特殊的專長領域，依目前管理單位人力資源現況並無法負擔本項工作的執行，亟需要具備專業之廠商來協助辦理安全監測相關檢查及監測資料判讀分析工作。

This project is routine surveillance works of Mudan dam for dam safety in 2016, Which been entrusted by South Region Water Resources Office, WRA, MOEA, (WRASB) owner of Mudan dam, was handled by Huan Jheng Engineering Consultants Ltd. Work Includes: 1. Analysis of monitoring data for dam safety; 2. In-situ facilities inspection; 3. Assessment of dam behavior and safety; 4. Inspection and review of monitoring instrumentation; 5. Technical advisory; 6. Results reports. According the results of this project, there are no obviously unusual behavior could threat the dam safety according the reading of functional instrument and inspection. The structure condition of spillway and outlet facilities are well, no abnormal deformation, settlement, over uplift force be found by monitoring and inspection. The left and right slope beside the dam, are no unstable sign could affect the function of Mudan dam. Beside, although some piezometers embedded in dam body are failured, at the condition of no obviously abnormal, the exist instrumentation are still reluctantly for dam safety mission. In future, if any sign of abnormal condition of dam is found, should have to strengthen the instrumentation for dam safety.
