擋土牆係用來撐擋土石,其承受之作用力為牆後之土壓力與水壓,如能有效降低水壓,對擋土牆之穩定性會大有助益。本研究即藉FEMWATER程式模擬探討兩條水平排水帶不同間距時之排水功效,數值模式先與室內試驗作對比印證,藉由試驗觀測與程式預測之洩降水位曲線呈現出相似之趨勢,驗證數值分析之適用性。接著探討兩條水平排水帶於不同間距配置時,其水壓及等勢能之分佈、滲流量之大小、水位洩降曲線及水壓力之大小,可以評估兩條水平排水帶於不同間距時之排水功效,進而歸納出最佳之水平排水配置。
Retaining wall is the structure sustaining pore water pressure and earth pressure so as to retain soil or rock. Therefore, it will contribute to the stability of the retaining if the pore water pressure can be effectively reduced by a subsurface drainage system. The purpose of this research is trying to find out the most efficient spacing of the drainage system by using a numerical program FEMWATER. Before the simulation study a comparison of the results from the built numerical model and a laboratory test was preceded to calibrate the parameter was going to be used. Results of the comparison have shown a similar trend of the water pressure curves produced by the numerical model and the laboratory test can be achieved. Results of the comparison have proved the feasibility of the numerical model simulation. With such a model study, the flux rate, the distribution of pressure head and total head, and the acting water pressure resulted from different spacing can be realized so that an assessment of the efficiency is also reached
