摘要
通过控制检测值之安全储备的方向性,可以降低工程施工质量的风险程度。以广东某高速公路路基压实度检测为例,从土的压实机理出发,对室内与现场的试验及检测结果进行分析,并利用核子仪法和灌砂法的对比资料,表明若使核子仪法具有一定的正安全储备,可以直接用于路基检测。
Controlling the orientation of testing value of safety margine can reduce the risk of engineering construction quality. A case study of a highway subgrade compaction is performed. The results of laboratory and in-situ testing are analyzed based on the principle of soil compaction. Comparing nuclear gauge method with sand cone method, the conclusion demonstrated that nuclear gauge could be used in testing subgrade while the nuclear gauge method has a certain positive safety margin.
