摘要
基于三点击实法的基本原理,提出了压实度的评估方法。该方法考虑了击实试样初始含水率与碾压现场含水率的误差,得到不同误差组合下的真实压实度,并由此得到真实压实度的取值范围、真实压实度大于某个临界值或设计指标的概率及近似压实度相比于真实压实度偏大或偏小的概率。该方法可获得压实度更加详细的信息.有利于对施工质量作出准确判断。
Based on the basis theory of three points compacted method, the compaction degree accessing method was proposed in this paper. In this method, the real compaction degrees with various error combinations were got by considering the error between initial water content of compaction samples and water content on rolling field. Then we can get the span of real compaction degree, the probability of real compaction degree bigger than a certain critical value or design index, the probability of approximate compaction degree bigger or smaller than real compaction degree. Based on this method, we can obtain more elaborate information of compaction degree. Therefore, it is better to evaluation the construction quality.
