一、概况比利时MoL地区地下190米处的粘土层向西北方向延伸并上升,在Antwerpen附近的Boom露头,因此称此地层为Boom粘土层。该粘土层是水饱和层,厚度约一百米,几乎是水平的(-180～-280米)。并处于二个含水层中间。上层是Autwerpen砂层,下层为Berg砂层。看上去粘土层非常均匀。经过数年的准备,现已在比利时核研究中心地下建造了地下实验室,为获取实验样 First, an overview Belgium 190 meters below the ground floor of the MoL clay layer extends northwest and rise in Boom near Antwerpen outcrop, so that this formation is Boom clay layer. The clay layer is a water-saturated layer with a thickness of about one hundred meters, almost horizontal (-180 ~ -280 meters). And in the middle of two aquifers. The upper is the Autwerpen sand and the lower is the Berg sand. Looks very uniform clay layer. After several years of preparation, underground laboratories have now been constructed underground in the Belgian Nuclear Research Center. In order to obtain experimental samples
