中文摘要 | 本文主要係利用實驗方式及依實驗結果所建立迴歸方程式來探討不同鹽份濃度流 體對不同土壤質地之毛管上昇高度與速率之影響。由實驗結果顯示,不論黏土或砂黏土,淡 海水之平均毛管上昇達最終上昇速率之時間最短,而對黏土而言,以淡水達最終上昇速率之 時間為最長,砂黏土則以海水達最終上昇速率之時間為最長。而最終上昇高度以淡水為最高 ,而淡海水為最低。由迴歸方程式計算得知,對同一時間而言,以淡水在黏土中之毛管上昇 高度為最高,而淡海水於黏土中之毛管上昇高度為最低。 |
英文摘要 | The purpose of this paper is to discuss the effects of salt concentration capillary rise in clay and sandy clay soil. Experiment of capillary rise and exponential regressin equations are used to solve this problem. According to the experimental results show that the mixture of fresh and salt water firstly reached the ultimate speed of capillary rise in both clay and sandy clay soil. For clay soil, the fresh water takes the longest time to reach the ultimate speed of capillary rise. Contrarily, the salt water is the last one to reach the ultimate speed of capillary rise in sandy clay soil. The fresh water has maximum ultimate height of capillary rise and mixture of fresh and salt water has the minimum one in both clay and sandy clay soils. For same time duration, the results calculated by regression equation show that the fresh water has maximum height of capillary rise in clay soil and mixture of fresh and salt water has minimum one in clay soil. |
