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.
