控制地下水位的田間排水溝間距簡捷計算方法 -
The author has analysed the seepage behavior of the fields in slope with the major parameter of the drain hole diameter and the length of hole. it is concluded that within the usual diameter of the hole, the size of the hole diameter has only minor influence on the field and the length of hole has more distinct influence. the author has analysed the effect of the center spacing change on the seepage field
其次，本文利用排水子結構法模擬排水孔，對排水孔孔徑、孔長多種布設方案的滲流場分佈對比分析，認為在通常可能取值的孔徑范圍內，孔徑變化對排水孔排水效果有影響，但影響較小；提出了孔徑選擇的原則；排水孔排水效果對排水孔孔長變化比較敏感，排水孔布設長度的選取應根據邊坡處治需要降低水頭的沿邊坡傾向方向的邊坡范圍來確定。
