雨水、灌溉用水或其它從別處流來之水，從地面向下移動進入土壤孔道內之行為可稱為入滲作用。而雨水降落至地表面後，一部份會自地表面入滲至土壤內，而另一部份將會形成地表逕流在地表面移動。為瞭解土壤噴灑黏著劑後地表下水分入滲特性之影響，本研究選用三種黏著劑搭配不同濃度之配比噴灑於台灣南部常見之風化泥岩土壤表面，並搭配室內進行添加黏著劑後對水分入滲之影響探討，期能對後續研究及施工設計做為參考依據。經由研究結果顯示，噴灑黏著劑後之泥岩將會增加水分入滲的速率，而黏著劑的配比濃度將會影響地表逕流量之大小，因此黏著劑之濃度若應用於坡地上應特別注意，並可搭配其他之工程及植生工法施作。

The runoff from rainfall and irrigate or the water flow from other somewhere, gradually moving from the soil surface to the bottom through the pores under this phenomenon can be described as infiltration function. After the rainfall drove to the ground surface, part of water will be infiltration into the soil and another will still flow on the soil surface. For understanding spraying cohesive agent for the infiltration effects, this research selected three kinds of cohesive agent with different concentration to spray on weathering mudstone soil, expectations for the future research and construction design. According to the experimental results, spraying cohesive agent will increase infiltration rate, but the concentration ratio of cohesive agent will effect surface runoff, so if applications at slope should be specific attention, and can be facilities for another engineering and vegetation method, to avoid affecting the development of slope protection and vegetation development.
