台灣南部地區水資源之供應，因豐、枯水期降雨量比例差異大(約9:1)，本地區之水源穩定，主要係藉由水庫之容量，台灣山坡地受降雨侵蝕沖刷，形成水庫淤積的問題，日益嚴重，尤以近年來集中降雨狀況，造成主要水庫蓄水容積遭土石淤積，致使水庫供應原水水量大幅減少。衝擊民生經濟之發展成長。
台灣南部地區主要有嘉義、台南及高雄都會區，而負責水資源蓄存及供應之主要水庫，則位於台南市與嘉義縣交界之曾文水庫、烏山頭水庫及台南市南化水庫，但高雄地區並無蓄存原水之水庫設施。
由於豐水期高屏溪川流水濁度太高(可達50000NTU)，使淨水廠之處理能力大幅下降，此時需有較乾淨之原水備援供應，為此吾人乃採以曾文水庫、南化水庫與高屏溪攔河堰水資源聯合運用方式，建構南化水庫與高屏溪攔河堰聯通管線以滿足大高雄地區之用水需求。
本研究主要係針對三項水庫原水供應必要設備之管理及安全維護需要，進行研究。第一項為水庫進水口淤積測量問題，第二項為輸水管路之鋼襯預力混凝土管(PCCP)管材結構安全問題，第三項為輸水管線受水流引發振動的問題。其中第一項水庫進水口前淤積測量之需求，係以開發耗能少，機動性良好優勢之小型水深量測船，使管理人員得以迅速辦理進水口前之淤積狀況之測量，藉以提供控制安全出水量資訊及輔助判讀水下安全狀況等管理需求。
第二項研究係針對原水輸水用大口徑PCCP管材之結構強度，以實驗方式獲得PCCP管材結構受內壓時預力鋼線良好情況下，及受內壓時預力鋼線斷裂情況下之結構強度變化，藉以配合渦電流非破壞檢測，掌握鋼線斷裂數量後，可即時研判出PCCP管材安全狀況，並提出具體PCCP管材維護保養更新計畫之時程，確保原水輸送之安全。
第三項研究係針對原水輸送管線受流體流動與支撐結構互置期間產生振動之問題，以理論數值計算分析成果，可掌握各式管線系統振動安全參數，再輔以振動監測系統，隨時監測，確保原水輸送之安全。
本研究成果可做為水庫管理機關，於設施操作管理及安全維護時之依據，俾能使水庫原水供應設備，於定期安全維護之良好管理計畫下安全營運。

The southern region of Taiwan mainly refers to Chia-I, Tainan and Kaohsiung metropolis, and the main reservoirs are Tsen-weng and Woo-Sentou reservoirs located at the border of Chai-I and Tainan. However, since there is no reservoir in Kaohsiung, the water for the habitants and industries in the metropolis is dependent on the Ping-Ding water treatment plant to pump water from the weir constructed in Kao-Ping River. In the rainy season, since the concentration of mud in the water pumped from the Kao-Ping river is too high (greater than 50,000 NTU) for the water treatment plant, it is required for the supply of clean water. To solve the last problem, a pipeline between Nan-Hua reservoir and Kao-Ping-River Weir is built to convey a part of water of Tsen-weng and Nan-Hua Reservoirs
This paper aims at the study of problems regarding the management and maintenance of facilities for water supply. The first problem is regarding the survey of slurry accumulation near the reservoir entrance. The second problem is regarding the safety of pre-stressed cylinder concrete pipes (PCCP’s). The third problem is regarding the vibration behaviors of the pipeline between Nan-Hua reservoir and Kao-Ping-River Weir. The purpose of this thesis is to find the solutions for the problems regarding the management and maintenance of water-supply facilities for the reservoirs located at southern region of Taiwan. To the last end, the following approaches are used:
For the first problem, a solar-power boat is developed; it can be easily used to measure the slurry accumulation near the reservoir entrance so that one may provide the information regarding the water supply, mud sediment, ect.
For the second problem, the non-destructive and destructive tests on the large-diameter PCCP composed of the pipeline are performed by using the strain gages.
Based on the above test results and the inspection results using Remote Field Eddy Current/Transfer Coupling (RFEC/TC) technique, one can predict the safety condition of the pipeline and present the schedule of repair or replace to assure the safety of the water-conveying pipeline.
For the third problem, this thesis presents a simple analytical method to calculate the lowest several natural frequencies and associated mode shapes of a fluid-conveying pipeline. In which, the effects of flow velocity of water, the internal pressure, the Coriolis force and axial load are taken into considerations.
It is believed that the research results of this thesis will be useful for the management and maintenance of the water-supply facilities.
