中文摘要 | 地下水壓影響邊坡的穩定,而地下水壓分佈又受地質材料的性質、土壤和風化層的厚度、岩層滲透異向性等的影響。本研究探討地下水滲透的異向性,對地下水分佈的影響。考慮層面或劈理面產生的滲透異向性,比較斜交坡、順向坡、逆向坡在相同降雨狀況下,地下水位與地下水壓分佈的不同。選擇廬山滑動邊坡建立水文地質模型,蒐集莫拉克颱風之雨量、地下水位隨時間變化的資料,用FEMWATER模式分析其三維狀況下地下水位因為降雨造成的變動,結果顯示逆向坡水位上升最多,其次是斜交坡,而順向坡最少。 |
英文摘要 | Slope stability is affected by groundwater pressure, of which the distribution is associated with the properties of geomaterials, the thickness of the weathered layer, permeability anisotropy. This study aims at the effects of permeability anisotropy on the distribution of groundwater. With the permeability anisotropy of cleavage, the groundwater levels of oblique, dip, and anaclinal slopes are compared under the same rainfall amount. The software FEMWATER was used to establish the hydro-geological model of an unstable slope at Lushan. Under the rainfall of typhoon Morakot, the rises of groundwater from the highest to lowest appear in the anaclinal, oblique, and dip slopes. |
