摘要

摘要: 堆石混凝土的密实度是表现耐久性和抗渗性的重要指标。为了研究其密实度检测方法的可行性，将堆石混凝土应用于兰新线乌西至精河段部分增建二线工程中，并在现场进行相关试验研究。其中在部分试验段，运用密实度计量分析法、钻孔取芯与芯样评定法、超声波检测及红外成像技术无损检测4种方法对堆石混凝土密实度进行检测，通过对检测结果的对比分析，发现应用红外成像技术的预埋管件无损检测方法能比较真实地检测出混凝土的密实情况，并具有操作简单和成本低廉的优点。

Abstract: Density is an important indicator with durability and impermeability of rock-fill concrete.In order to study the feasibility of density detection method.Rock-fill concrete was applied to the additional second-line project of Lan-Xin railway between Wuxi and Jinghe,and the related experiments and study on that field were taken.Four methods,such as density measurement analysis,borehole core samples and core assessment,ultrasonic testing method,embedded tube nondestructive testing method,were used in some experimental section to detect the density of rock-fill concrete.And through the comparative analysis of detection results,it was found that the embedded tube nondestructive testing method in which the infrared imaging technology was used could detect the dense situation of concrete veritably with the simple operation and cheap cost.
