Experiment on Seepage in Varied Section of Core Wall for Fill Dam Design

필댐 제체심벽(堤體心壁)의 단면변화(斷面變化)에 대한 침투류해석(浸透流解析)에 관한 실험적(實驗的) 연구(硏究)

This thesis, intended to establish the design criteria of core wall of a Fill Dam, has determined after a series of twenty one analytic experiments on the seepage flows in various types of core wall that the rates of rise and fall of the seepage flow changing in accordance with the variation of core wall cross section, which is to say, the transformation of slope inclination. Particularily the appropropriate design inclination was examined for the sloped core wall. Putting the resulting values into the existing approximate theoretical function has revealed the volume of theoretical seepage flows. With this result, the experiment values was compared and interestingly enough, a theoretical formula was found which is considered to be the nearest one to the resulting values of the experiment. It is also discussed in the papers that the seepage alignment and flows in the sloped core wall section that inclined to the upstream and the adoptability of the theoretical function which has been known up to present. Based on the above mentioned study it is anticipated that thesis should be available for determination of the cross section in the core wall design of a Fill Dam as large amount of references as it can be.

본(本) 논문(論文)은 필댐에 있어서 최적심벽(最適心壁) 설계(設計)의 기준(基準)이 될 수 있도록 21개(個)의 심벽모형별(心壁模型別) 침투류(浸透流) 해석(解析)에 대한 실험(實驗)을 실시(實施)하여 경사면(傾斜面)의 기울기 변화(變化)로 침투류량(浸透流量)의 증감율(增減率)에 대해서 규명하였고, 특히 경사심벽(傾斜心壁)에서의 적정(適定) 설계경사(設計傾斜)를 찾아 보았다. 그리고 현재(現在)까지 발표(發表)된 근사이론식(近似理論式)에 실험치(實驗値)를 대입(代入)하여 이론침투류량(理論浸透流量)을 구(求)하고 실험치(實驗値)와 비교연구(比較硏究)하였으며, 검토결과(檢討結果) 실험치(實驗値)에 가장 가까운 이론공식(理論公式)도 찾았다. 또한 상류(上流)로 기울어진 경사심벽(傾斜心壁)에서의 침윤선형(浸潤線形)과 유출점(流出點)에 대해서도 고찰(考察)하고 현재(現在)까지 발표(發表)된 이론식(理論式)의 적합유무(適合有無)도 검토(檢討)하였다. 이상(以上)을 연구(硏究)하여 필댐의 심벽설계시(心壁設計時) 최적단면결정(最適斷面決定)을 위한 보다많은 자료(資料)를 제시(提示)하고자 하였다.
