利用剖面重力测量数据反演深圳市地下断层参数

Inverting Underground Fault Parameters of Shenzhenfrom Profile Gravimetry Data

  • 摘要: 目的 探测深圳市地下断层参数对该地区的规划建设、抗震设防和可持续发展具有重要意义。利用人机联作选择法反演了深圳市两条测线的断层参数,反演结果表明:两条测线的正演模型与观测值之间相对误差分别为4.51%和4.26%,计算结果可靠;断层从地下4km 附近开始出现破裂信号,至17km 附近消失,倾角约为70°,属于倾角较大的正断层;断层位置与深圳市地形起伏可能存在一定相关性。研究结果与地质及地球物理勘探结果具有较好的一致性,验证了剖面重力测量数据反演深圳市地下断层参数的可行性和有效性。

     

    Abstract: Objective It is great significance for construction planning,seismic fortification and sustainable devel-opment to determine the fault parameters of Shenzhen.The parameters of faults under two surveylines in Shenzhen are inverted by a human-computer interaction method in this paper.The resultsshow that:firstly The relative errors between a forward model and observations of two survey linesare 4.51% and 4.26%,and the computed results are reliable;secondly The range of faults is aboutfrom 4km to 17km and normal faults with 70degree dip angles approximately;finally The locations offaults may be correlated with the topography in Shenzhen.The results are in accordance with othergeological,exploratory and geophysical data.Our results show that profile gravimetry data is feasiblefor inverting fault parameters in Shenzhen.
