摘要
以潮州港华北片LNG气化站工程场地为例,探索了"网格化"、垂直目标断层测线布置下的各测点氡气、汞气含量等值线图区分场地断层气异常"真"、"假"方法。以等值线图中各测线上异常测点的分布特征为依据,若出现平行目标断层走向的规则异常带,则分布在异常带上的测点异常值与断层活动有关。
Taking the gasification station site of north Ganghua,Chaozhou as example,it is a requested method of consistency isoline to differentiate fault gas abnormal value.It＇s true or false,which we probing radon or mercury,by the vertical girding measuring line.According to measuringlines＇ abnormal value of distribution rule,we decide which are or not to caused by active fault.If there is an abnormal zone,which is parallel the trend of objective fault,we consider these abnormal value caused by active fualt.
