摘要
198 9年 3月 1日起施行的GBJ 12 3 88土工试验方法标准中 ,在土的界限含水量测定方法中规定了液、塑限联合测定法 ,通过总结多年的实践工作经验 ,介绍了该方法在实际工作中存在的主要问题。以 2 0 0多组试验数据为依据 ,对含水量与圆锥下沉深度之间的线性相关关系进行了分析研究 ,找出了相关系数与规范规定的差值之间的关系 ,在作图法的基础上提出了计算法 ,并提出了符合规范要求及实际工作的控制指标。
In 《Civil Test Method Standard》GBJ123 88 impleme nted in 1st Mar, 1989, there is liquid plastic limit combined measurement in th e measurement of moi sture content. Through summarizing many years' practice experience, major proble ms in practice work are discovered. More than 200 group of experiment datum are collected, linear dependence relation between moisture content and the fall in d epth of cone is analyzed and researched and relation between correlation coeffic ient and difference specified by the specification is found. The numeration is p ut forward on the base of graphing method, at the same time, control index meeti ng specification requirements and actual work are brought forward.
