| 摘 要： | 对成都平原8条具有代表性的隐伏断层进行氡气测量，其研究表明其氡气特征除新津断层外其余都表现为多峰异常，成都平原隐伏断层大多为规模较大的断裂带，可能有多个分支断层组成。位于成都平原中西部边缘的隐伏断层活动性强于东部的隐伏断层，表明成都平原隐伏断层活动性受龙门山构造的控制。通过该研究，为监测隐伏断层的地震活动性提供了新的途径。

| Abstract: | Most of buried faults on the Chengdu Plain large fault zones composed of multiple branch faults. Radon survey on the eight buried faults on the Chengdu Plain shows multiple peak anomalies with the exception of the Xinjin fault. Activity of the buried faults on the western margin of the Chengdu Plain is stronger than the that of those in the east based on radon anomalies, which indicates that the buried faults on the Chengdu Plain were controlled by the Longmenshan tectonic zone. |
