雨水、灌溉用水或是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稱之為入滲作用。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對於地表下水份入滲特性之影響,本研究選用三種黏著劑搭配不同濃度之配比噴灑於紅土及泥岩上,並搭配室內入滲試驗進行添加黏著劑後對水份入滲之影響探討,期能對日後研究及施工設計做為參考依據。 試驗結果顯示,噴灑黏著劑後之泥岩及紅土將會增加水份入滲的速度及深度。但黏著劑的配比濃度將會影響地表之逕流量大小,因此黏著劑若應用於坡地上應特別注意其調配濃度,並可搭配其他之工程及植生工法施作,避免影響現地坡面保護及植生復育之發展。
The water of the rainfall and the irrigate or the water flow from other 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 infiltrated into the soil and another will be runoff on the surface. In order to understand spraying cohesive agent for the infiltration effects , this research selected three kinds of cohesive agent were selected with different concentration to spray on common on Laterite and Mudstone, with laboratory experiments to spray cohesive agent for the infiltration effect 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 . If applications at the 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.
