摘要註:	透水性鋪面具有減少地表徑流，預防都市洪災等優點。然而透水性鋪面因承載力有限，目前多應用於低交通量地區。現今透水性鋪面結構之基層，多挖除現地土壤，以承載力較佳之砂與礫石等粗粒料取代，耗費購買及運送粒料之經濟成本與環境成本。為使透水性鋪面可更加廣泛應用、提高鋪面品質、友善環境與降低花費，本研究針對土壤穩定方法改善現地軟弱土壤應用於透水性鋪面之底層進行初步之研究。本研究以水泥及飛灰作為土壤穩定材料，改善軟弱土壤之力學性質，藉由無圍壓縮試驗，探討不同條件下之改善效果，與原始土壤試驗結果比較及討論。並以室內透水試驗所求得之滲透係數作為土壤透水性之依據。接著以分離元素法分析軟體PFC3D建立數值模型，模擬無圍壓縮試驗之試體受壓行為，並求取可代表實驗結果之微觀力學參數，以此參數模擬透水性鋪面之底層承受靜態載重時之力量分布狀態，探討原始土壤與穩定處理土壤模擬結果之差異性。實驗室試驗研究結果可知，試體之較佳養護方式、固定比例下水泥與飛灰之添加量、拌合含水量、無圍壓縮強度隨相對夯實度降低而減小、土壤之滲透係數隨相對夯實度降低而增加，飛灰佔水泥之比例降低時，透過降低相對夯實度而提高滲透係數之效果較佳。綜合實驗室實驗結果，採用適當之土壤穩定材料添加量及配比並搭配降低相對夯實度，可兼顧承載力及透水性之需求。數值模擬無圍壓縮試驗部分，以試誤法求得各項微觀力學參數之設定值，在模擬過程中歸納出各項參數調整對模擬結果之影響，最後決定兩組參數組合分別對應原始土壤及添加土壤穩定材料之實驗結果，建立土層模型，模擬透水鋪面底層承受靜態荷重之力量傳遞分佈情形，發現代表添加土壤穩定材料之土層模型具有較佳之力量傳遞分佈，原始土壤之土層模型則顯示應力多集中在局部區域。 Permeable pavement has the advantages of reduction of surface runoff, prevention of urban flooding and so on. Permeable pavement is used to be applied to low traffic volume areas because of the limited loading capacity. Instead of in-situ soil, the base of permeable pavement usually uses graded gravel and sand. The graded gravel is usually obtained and delivered from other places, and this raises the cost and leads to environmental pollution. However, in-situ soil can be used to reduce costs and environmental pollution, if its engineering properties are improved. In this study, the feasibility of applying soil stabilization method to improve the engineering properties of in-situ soil so that it can be used as the base of permeable pavement is preliminarily researched.In this study, cement and fly ash are used as the materials of soil stabilizer. The results of unconfined compression test under different conditions were discussed and compared. The permeability is obtained from the laboratory constant-head test. In order to get parameters for numerical simulation, distinct element method is adopted to build a numerical model to simulate unconfined compression test.As the content of cement and fly ash varies, the test results show that higher percentage of stabilizer results in higher unconfined compression strength and more brittle failure. When the relative compaction varies, the results show that unconfined compression strength reduces when the relative compaction decreases. As the relative compaction is getting lower, the peak value of stress-strain curve becomes less obvious and failure occurs at a smaller strain. The soil permeability at various compaction degrees is also studied in this study. The results show that it is nearly impervious at 100% compaction degree, and permeability coefficient increases as relative compaction degree decreases. For better permeability, the fly ash content is reduced to raise the porosity of the specimen. Test results show that less fly ash content leads to better permeability.In the section of numerical simulation, the micro-mechanical parameters are determined by trial and error method. The effects of various parameters on simulation results are summarized. Finally, two parameter combinations corresponding to the original soil and stabilized soil are used to build two models to simulate base of pavement. Simulation results show that the stabilized soil model has a better stress distribution, while the original soil model displays a local failure situation.
