查询词典 water content

A series combined test method tests were performed to determine the liquid-plastic limits of different samples of fine grained soil and silty sand. The result showed that the loglog relationship between the depth of penetration of fall cone and the water content of some samples were clearly not linear, and the liquid-plastic limit could not be obtained according to the linear relation. Effective test data could not be measured within the three arranges of water contents proposed by the present standards. The dependability was necessary to discuss about the liquid-plastic limit test results obtained from three arranges.

采用液、塑限联合测定法针对部分细粒土和粉砂进行液、塑限测定时，发现对于部分细粒土在双对数坐标上圆锥下沉深度与含水率之间的关系并非线性关系，无法依据线性关系确定液、塑限：采用规程建议的三个含水率范围有时根本无法获得有效试验数据；采用规程建议的三个含水率范围确定得到土的液、塑限试验结果的可靠性有待商榷；采用直线段试验数据确定的液、塑限进行分类可能出现相互矛盾甚至错误的结果。
