摘　　要：以辽宁省绥中县平台隧道工程地质勘察为例,说明隧道在通过具有放射性的花岗岩区时,可通过放射性测量与试验,对隧道区花岗岩岩体放射性及铀矿物含量作出准确分析,为隧道建设的适宜性作出准确评价,分析评价结果表明:本工程地质勘察中放射性物质测量数值均小于规范数值,隧道整体天然放射性环境较为安全,适宜修建隧道。Taking the engineering geological survey of the platform tunnel in Suizhong county,Liaoning province as the example,it is explained that when the tunnel passes through the granite area with radioactivity,the radioactivity and uranium mineral content of the granite rock mass in the tunnel area can be accurately analyzed through radioactivity measurement and test,and the suitability of the tunnel construction can be accurately evaluated. The analysis and evaluation results show that: the measured values of radioactive substances in the engineering geological survey are less than the standard values. The overall natural radioactive environment of the tunnel is relatively safe and it is suitable for tunnel construction.
