| 摘 要： | 密实度是反映堆石混凝土强度、耐久性的重要指标，可通过孔隙率的检测来评定。通过采用多种检测方法可知：密实度计量分析法、钻孔取芯与芯样评定法、预埋管件无损检测法均能较准确的计算混凝土的孔隙率，超声波检测法只能宏观评定；密实度计量分析法实际操作比较困难，钻孔取芯与芯样评定法属于半破损检测；预埋管件无损检测首次将红外成像技术应用于混凝土的密实度检测之中，方法简单、造价低廉、数值准确，建议对其进行推广使用。

| Abstract: | Density is an important indicator for the intensity and durability of boulder concrete,which may be assessed with the detection of its porosity.After detecting its porosity by different detecting methods,such as the density-analyzing method,the boring and sampling method,and the non-damage detecting method,all of which can help us comparatively accurately calculate its porosity,and the ultrasonic testing method,which can help us make a macro evaluation of its porosity.We find the density-analyzing method co... |
