舉凡雨水、灌溉用水或是其它從別處流來的水,從地面向下移動進入土壤孔道內之行為均稱之為入滲。而降水到達地表面後,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對地表水分入滲特性之影響,本研究乃選用三種常用的黏著劑,搭配不同濃度之配比,噴灑於臺灣南部常見之紅土及泥岩上,以室內試驗方式探討噴灑黏著劑後對土壤水分入滲之影響,期能提供作為日後研究及施工設計之依據。經由研究結果顯示,噴灑黏著劑後之泥岩及紅土會增加水分入滲的速度,而黏著劑的配比濃度會影響地表之逕流量大小,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為佳,以免影響現地坡面保護及植生復育之發展。
In general, the rainfall and the irrigate water or the water flow from somewhere, moving from the soil surface to the bottom through the pores under the act can be described as infiltration function. After the rainfall drove to the ground surface, part of water will be infiltration into the soil and water will be runoff on the surface. For understanding spraying cohesive agent for the infiltration effects, this research selected three kinds of cohesive agent with different concentration to spray on Laterite and Mudstone, 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.
