摘要

由於目前國內於鋪面透水設計及基地保水力評估上，缺乏相關之設計參數參考，因此本研究之目的為對透水效益與透水面積比之關係，採模組試驗研究並以美國環保署所發展之PCSWMM程式結合分析，加以探討不同程度之透水面積比例時，所產生之透水效率，目標以求得最佳化透水設計之關係參數，提供未來於透水性設計上之參考。
本研究乃為設計一組室內控制試驗，盼能藉由該試驗探討於同一降雨條件控制下，基地內不同比例透水性鋪面之鋪設方式，其產生之地表逕流與入滲量間的關係。採用長寬皆為80㎝之方型透明壓克力箱為試驗槽體，其高度為100㎝，於上下各有一個出水口，於試驗箱上方擺設一人工降雨器，藉由同一降雨條件下，於建築基以建築物佔基地20%、40%、60%的比例，及人行道不透水舖面20%、40%、60%的比例試驗。所蒐集到之地表逕流與滲流量，結合PCSWMM程式輔助模擬，將各透水性鋪面鋪比例達穩定滲流之延時與穩定入滲量之曲線交點得最佳化之基地透水面積，決定出基地保水之最佳透水性鋪面鋪設比例。設計於建築基地形式下最佳透水面積百分比約為54%，人行道約為68%。

Due to inadequacy of relevant descriptions and design regarding the assessment of pavement permeable design and construction side guaranty water for reference nation wide, the purpose of this study specifically is to discover the correlation between the effectiveness of permeation and the proportional dimension of it. By utilizing module testing research and basing on PCSWMM developed by Environmental Protection Agency of the United States, this study probes to discuss the extent of effectiveness of permeation resulting by different proportion of permeable dimension. It is hoped to obtain relations description for optimal permeation design. This study serves as reference information for the design of permeation in the future.
The design of this study is to put a control group interiorly. Under the same raining condition, using different proportion of permeation (water-proof pavement 20%, 40% and 60%) to pave on the construction site and the pedestrian, It generates surface runoff and infiltration of which the correlation is crave to be found.
A transparent sand box is used experiment sink, and its height is 100 centimeter, the length and width are both 80 centimeter. The box has a water exit located above and below respectively, and an artificial raining machine is placed above the box. Under the same raining condition, the collected surface runoff and infiltration can determine the optimal proportion of paving permeable base floor for the design of water reservation.
Given the duration and correlation of surface runoff and infiltration gained from the experiment, PCSWMM program is utilized to assimilate and use the duration, of which the permeable pavement proportion, achieves steady infiltration as well as steady infiltration. As a result, a crossing point on the curve suggests that the optimal dimension of permeable design is 54 % built as construction base and 68 % as pedestrian.
