深圳市断裂新活动与地震研究进展

回顾了深圳地区断裂最新活动性和地震的研究历史,总结了前人所作的主要工作与认识,以此为基础进一步介绍了深圳市活断层探测与地震危险性评价项目的最新工程探测成果与研究进展。项目选择了横岗-罗湖断裂、莲塘断裂、温塘-观澜断裂为研究对象,采用了卫星遥感解译、微震精确定位、野外地震地质调查、钻孔和探槽探测、浅层地震勘探、深部结构大地电磁阵列探测、地下电磁波勘探等工程技术方法,对断裂的近地表及中深部结构特征、新活动性和地震危险性进行了探测与评价,获得了一系列新的认识。最后,结合深圳市断裂构造运动和地震研究现状与存在的问题,提出了今后开展工作的若干建议。

Advances on New Activity of Faults and Earthquakes in Shenzhen City

The paper reviews the history of earthquakes in Shenzhen city, and sums up the the research on the latest activity of faults and previous work and main cognition. On the basis of this, the latest engineering detection results and research progress of the project on active fault surveying and earthquake risk assessment in Shenzhen city are introduced. In the project, we study Henggang-Luohu fault, Liantang fault and Wentang-Guanlan fault with the help of the satellite remote sensing interpretation, the microseism pinpoint, the seismogeological survey, the drilling and the trench detection, the shallow seismic exploration, the magnetotelluric array detection and underground electromagnetic prospecting. The features of near surface fault and mid-deep structure, new new acknowledge are ob activities of the above faults and earthquake risk are assessed, and some tained. Finally, some suggestions are faulted structure activities in Shenzhen city and existed problems proposed by the combination of of earthquake risk assessment.
