為確保牡丹水庫之安全及穩定，大壩及溢洪道於施工期間埋設有多項監測儀器，藉由儀器所量測數據可研判壩體行為及安全性，由於該項工作涉及領域廣泛並具專業性，爰擬辦理本委託技術服務工作

his project is routine surveillance works of Mudan dam for dam safety in 2013, Which been entrusted by South Region Water Resources Office, WRA, MOEA, (WRASB) owner of Mudan dam, was handled by Huan Jheng Engineering Consultants Ltd.. (Huan Jheng). Work Includes: 1. Analysis of monitoring data for dam safety; 2. In-situ facilities inspection of safety; 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 work, there are no obviously unusual behavior, which could threat the dam safety, be found from the reading of functional instrument and inspection of dam in this year. The structure condition of spillway and outlet facilites are well, no deformation, no settlement, no over uplift force be found by monitoring and inspection. The slope of access road of spillway, which sliding before, is stable in this year, but the right side slope was slightly moving after strong rainfall in September. For stability of these two slopes, drilling horizontal drainage pipe is suggested to control the ground water level rised up during strong rainfall. Beside, although some piezometers embedded during dam constructure are failured, at the condition of no obviously abnormal, the exist instrumentation still reluctantly for dam safety monitoring works. In future, if abnormal seepage condition of dam is found, should have to strengthen the capability of monitoring of dam.
