為水文地質調查而取土样作分析時,分析其孔隙度,顆粒組成及滲透係數。分析的目的主要是为测定滲透係數。利用孔隙度及顆粒組成可求渗透係數,其計算用各种公式介紹 如下。为便於讀者利用方便,作成表格加以說明(如下麦)。利用公式時,要首先考慮应用範圍,尽可能用幾個公式計算,然後將其計算結果加以比較。
When taking soil samples for hydrogeological survey for analysis, the porosity, particle composition and permeability coefficient were analyzed. The purpose of the analysis is primarily to determine the permeability coefficient. Permeability coefficient can be calculated by using porosity and particle composition, and its calculation is described as follows with various formulas. To facilitate the reader to facilitate the use of forms to explain (as wheat). When using the formula, we must first consider the scope of application, as far as possible with a few formulas, and then compare the results of their calculations.
