本研究採用 SEEP/W 模式模擬烏山頭水庫半水力淤填式壩堤之穩態滲流
過程,並與現地量水堰監測資料比較,探討該壩體之滲流特性及合理滲流水
量,建議正確的分析方法與改進事項。首先,本研究採用與第四次安全評估相
同之大壩標準橫斷面及相關設定,複算黎明工程顧問公司的烏山頭大壩滲流分
析成果,以檢核分析條件與SEEP/W 模式的正確使用。在複算完成後,再逐一
加入現地條件,包括:基岩、水庫淤積、排水系統佈置及實際壩體材料組成及
分佈等,並檢討其對滲流水量之影響與模擬成果之合理性。經比較滿水位El.
58.18 m 的滲流水量,發現單一水力淤填斷面因素約增加63%的滲流水量。
當以實際壩體條件模擬得到合理的滲流水量後,本研究選取6個烏山頭大壩的代表性斷面,各自模擬二維穩態滲流,最後將全壩體各區段滲流水量與量水堰測得的實際水量比對,結果顯示本研究模擬之滲流水量比歷次安全評估分析的滲流水量大,更為量水堰量測水量之1.6 倍。由於4 座量水堰實測水量均相當程度小於模擬水量,究其原因可能是壩體內的滲流水有明顯的側向流動,且不經排水暗渠排出壩體所致,造成此現象的原因可能也和水力淤填斷面不夠均質有關。
在改善模擬方面,本研究模擬大壩二維穩態滲流,水庫水位變動時滲流水量會立即改變,如果採用暫態模擬,可更符合現地滲流特性,或可得到更精準的分析結果。而壩堤內應有側向的滲流現象流動,因此宜考慮採用三維模式模擬,以更精確描述水力淤填壩體內的滲流過程。最後針對排水暗渠的阻塞及高程特性,宜配合修正邊界條件,以求得更正確的滲流水量。
SEEP/W model simulations Wu shan tou Reservoir Semi-hydraulic Filled Dam, and with weir monitoring data comparison of the dam's seepage flow characteristics
and reasonable flow, with the same fourth dam safety assessment standards and related cross-sectional setting, recalculation Liming-Engineering-Consultants dam seepage analysis results, to check conditions and nuclear analysis of SEEP / W model, and to join to including: rock, sedimentation, dam drainage system layout and the actual composition and distribution of materials, and review the impact of water seepage and simulation results of the reasonable. The water level El.58.18m of seepage, a single cross-section factor increased by about 63% of the seepage.
Six representative cross-section ,two-dimensional steady-state flow simulation, to the whole dam seepage of water in each section and the amount of water weir measured than the actual amount of water, than in previous simulations of the flow of water seepage water security assessment analyzes more water weir measurement of 1.6 times As the four weir water are considerable smaller than the measured simulation of water, he reason may be water seepage within the dam have
significant lateral movement, and not caused by the drainage culvert discharge, this phenomenon due to silt and water is not homogeneous the filling section.
Changes in water flow when the reservoir water level will change immediately, if the use of transient simulation, to be more in line with the current flow characteristics, or obtain more accurate results. The dam should Tsutsumiuchi lateral seepage flow phenomena, it is appropriate to consider three-dimensional model simulations, in order to more accurately describe the water flow within the deposition process to fill the dam. blocking culverts for drainage and elevation features, with the correct boundary conditions should, in order to seepage of water more correct.
