公路工程基层施工中,压实度是质量管理的重要指标。本文是阐述采用天然砂砾作基层时,其压实标准的确定及应注意的问题。我们是以“确定标准干容重”、“现场压实度评定”、“现场试验分析”三项为主题。通过大量的现场试验数据,用数理统计分析的方法,在对现场基层压实度进行检验的过程中提出问题,以测试所得的实际成果为验证、推理、解答问题的依据。1986年,在库尔勒一轮台的阴霞地段进行改建工程。线路地处西北干旱区的一荒漠过干区,地下水位浅,土盐渍化严重。原路基土0～80
Road construction grassroots construction, compaction is an important indicator of quality management. This article elaborates the compaction criteria and problems that should be noticed when natural gravel is used as grassroots. We are based on “to determine the standard dry weight,” “site compaction assessment”, “field test analysis” three themes. Through a large number of field test data, with the method of mathematical statistics and analysis, the paper puts forward the questions in the process of testing the compaction degree of the grassroots in the field, and verifies, infers and answers the questions based on the actual results obtained. In 1986, reconstruction work was carried out in the shade of a round of Korla. The line is located in a desert dry area in the arid northwestern area with shallow groundwater level and serious soil salinization. Subgrade soil 0 ~ 80
