摘要
该文用双环法和人工降雨方法分别对遂宁组紫色土的渗透性能进行了研究,其结果表明:(1)双环法和人工降雨法测定的土壤稳定入渗速率分别为101mm/h和18mm/h;(2)雨强对土壤稳定入渗速率无显著影响;
The permeability of purple soil is studied by means of double ring method and rainfall simulator respectively.The result shows:(1)the measured constant infiltration rates by double ring and rainfall simulator are 101 mm/h and 18 mm/h respectively.(2)the rainfall intensity has no significant influence on constant infiltration rate.(3)there is no influence on constant infiltration rate by plough.
