摘要
本文根据在盐碱地进行竖井排水改良的试验研究,得出了在含水层具有弱承压性的弱透水土层地区,竖井排水仍是防治土壤盐碱化的有效措施。它具有排水速度快,强度大及排水效果好等优点;并具有土壤脱盐率高,脱盐深度大及全剖面脱盐的效果。文中根据排水试验资料分析所得的计算式,可供同类地区参考。
According to the experimental research of drainage by wells in salinc-alkali, it has been found that in the areas whcre the aquifer has weak artcsian pressure and permeability, drain age by wells is still cffcetive for prevention and trcatment of soil salinization; drainage by wells has advantages of high speed, great intensity and high cffectiveness; it can achieve the effect or high rate and great dcpth of dcsalting and dcsalting on the whole profile. The formulas presented in this paper can used in similar region.
