堤坝与道路结合工程路基压实度取值的讨论

Discussion on subgrade compaction degree of project for embankment combined with road

堤防的填筑压实度主要由轻型击实标准确定,而公路的路基压实度主要应用重型击实标准,因此在路与堤坝结合设计时,规范的适用范围有重叠,给压实标准的选取带来困难。文中应用统计的方法,结合以往工程试验数据,对压实度的取值范围进行初步讨论。

The compaction degree of embankment filling is mainly determined by the light compaction standard,while the compaction degree of highway subgrade is mainly determined by the heavy compaction standard.Therefore,the application scope of the code overlaps when designing the combination of road and embankment,which brings difficulties to the selection of compaction standard.In this paper,the value range of compactness is discussed preliminarily by using statistical method and combining with previous projects test data.
