项目摘要

The measurements of Atterberg Limits, specific surface area and micro pore volume on about 50 soil samples that taken in all lwate prefecture were practiced. The results are as follows.1. In the case of same diameter range of cylinder pore model, the results of Cranston-Inkley method and Model Less method bear a close resemblance. The same statements are true as lnnes method and Model Less method on plain plate model.2. Specific surface area of samples ( particle size is 0.42mm under ) most valued 10-50m^2/g. And micro pore volume valued 0.01-0.06ml/g. But only volcanic ash soils valued 110m^2/g, 0.11ml/g at maximum respectively.3. The values of about 80 % of specific surface area were came out of the micro pore column.4. Specific surface area had mutual relations with physical properties of soils (Liquid Limit, Plastic Limit, pF3.0 moisture, pF4.2 moisture). And it could be illustrated that the correlative formulas between physical properties of soils and specific surface area pointed out the exponent one.

对日本岩手县全境约50个土样进行了阿太堡限、比表面积和微孔体积的测定。研究结果如下：1.在圆柱孔模型直径范围相同的情况下，Cranston-Inkley法和ModelLess法的计算结果非常接近。在平板模型上，与Lennes方法和无模型方法的结论相同.样品的比表面积（粒径为0.42mm以下）最大值为10-50m^2/g。微孔容积为0.01-0.06ml/g。火山灰土最高值分别为110m^2/g、0.11ml/g.微孔柱测得了约80%的比表面积.土壤比表面积与土壤物理性质（液限、塑限、pF3.0水分、pF4.2水分）之间存在相互关系。说明土壤物理性质与比表面积的相关关系式均为指数关系式。
