地质雷达在混凝土面板堆石坝面板脱空检测的应用分析

APPLICATION ANALYSIS OF GEOLOGICAL RADAR IN THE VOID DETECTION OF CONCRETE PANEL ROCKFILL DAM

在水利工程中,混凝土面板堆石坝是一种应用非常广泛的筑坝类型之一,选择该类型的主要原因是混凝土面板堆石坝建筑材料可就地取材,这一优势可节约大量材料成本,因此面板堆石坝在水利工程建设项目中的数量也越来越多,在堆石坝面板施工后,坝体填筑料的自然沉降及碾压不密实等原因会造成面板脱空现象。对于这类缺陷,坝体结构稳定存在较大隐患,面板又属于关键部位,不宜采用破坏性的检测方式,采用地质雷达可直观反应出堆石坝面板脱空位置的具体类型及情况。

Now water conservancy project type,concrete panel rockfill dam is one of the widely used dam type,the main reason is the type of concrete panel rockfill dam building materials can local materials,this advantage can save a lot of material cost,so the panel rockfill dam in water conservancy engineering construction project is more and more,after the rockfill dam panel construction,due to the natural settlement and compaction will cause panel empty phenomenon.For this kind of defects,there are great hidden dangers in the stability of the dam structure,and the panel is a key part,so it is not suitable to use destructive detection methods.The geological radar can intuitively react the specific type and situation of the vacancy position of the rockfill dam panel.
