| 摘 要： | 盐田是卤水提钾生产中最基本的组成部分,在选址中,需要确定选区是否存在连续的粘性土层作为盐田隔水底板。但由于选区面积大,试样数量巨大,实验周期长,经费投入大,无法满足要求。运用数理统计原理,在全区范围内均匀选取具有代表性样品用洗盐后的塑性指数IP'与洗盐前的塑性指数IP进行数理统计分析,得出回归方程IP'=2.27400+0.98118×IP,用此方程可得出洗盐后盐渍土的塑性指数,用于全区的岩土分类定名,不但满足了要求,也产生较大经济效益。

| Abstract: | Saltfield is the basic component part of kalium collecting production from salty sand,it is necessary to ensure if there is a serial stick soil layer being the base to separate the soil during the site selection;and which is difficult to satisfied all the requirements as its large selected area and lots of sample quantities and long test period as well as the lots of cost,by using the mathematical statistics theory,study the plastic index(IP/=2.27400+0.98118×IP)and correlation coefficien(tr=0.95406)of choose equably typical specimen before and after salt wash,which is easily for the classification and denomination of the salty soil. |
