本文针对宕渣路基,提出了一种基于落球检测技术的均匀性检测方法。宕渣是浙江省特有的一种土石混合料路基填料,不均匀性严重,对路基性能的影响不容忽视。但长期以来,采用挖坑灌砂法等检测压实度(即固体体积率法)无法对大面积的路基的均匀性进行检测。落球检测技术则是近年发展起来的一种现场岩土材料力学特性的快速检测技术。本文研究了基于落球检测技术的宕渣路基均匀性检测方法,结果表明其对保证路基工程质量、提高及耐久性十分有意义。
In this paper, aiming at the slag embankment, a method of uniformity detection based on falling ball detection technology is proposed. Slag slag is a peculiar kind of soil-rock mixture in Zhejiang Province, which has serious non-uniformity and can not ignore the influence of subgrade performance. However, for a long period of time, the compaction degree (that is, the solid volume fraction method) by means of digging and sand filling method can not detect the uniformity of a large area of subgrade. Falling ball detection technology is developed in recent years, a rapid detection of geomechanical properties of geotechnical materials. In this paper, the detection method for the uniformity of slag dregs based on the falling ball detection technology is studied. The results show that it is very meaningful to ensure the quality, improvement and durability of the subgrade engineering.
