附加质量法在粗巨粒土压实干密度检测中的应用

APPLICATION OF ADDITIVE MASS METHOD TO THE DRY DENSITY MEASUREMENT OF ROUGH -HUGE AGGREGATE SOILS

高填方工程中粗巨粒土压实质量检测的传统检测方法大多有其弊端和适用性,难以满足大规模施工中压实度质量检测控制上的实际需要。在某机场高填方工程中,采用附加质量法对粗巨粒土压实干密度进行无损检测。试验结果表明,附加质量法具有检测效果好,速度快,对被测土层无损伤等优点,是一项很有发展前景的无损检测技术。

The traditional methods for density measurement of rough-huge aggregate soils have both applicability and limitation in the high-fill engineering,so it is difficult to meet the demand of the density control in large-scale construction.In a high-fill airport,the non-destructive testing method of additive mass is applied.The testing results indicate that it is not only rapid,portable,non-destructive and precise,but also suitable for density measurement of rough aggregate soils.It has proved that method of additive mass is obviously effective and shows fairly good prospects for its application.
