Abstract:Based on the data of precise leveling survey in 2001、2005 and 2009 around the Capital Circle area,the elevation variation induced by subsidence at the mobile gravity measuring points were calculated for the data from 2001 to 2009 in this area. With Bonguer correction formula of high precision, the gravity variation induced by subsidence at the mobile gravity measuring points from 2001—2009 in Capital Circle area were obtained from the varied elevations at the points. The results show that, the gravity variation induced by subcidence at the mobile gravity measuring points can be calculated accurately with precise leveling data.
