摘要
本文首先对任丘~保唐~沧州一带的重力复测资料进行了拟稳平差处理、地下水和地形变改正,然后对该区1986年以来出现的重力场变化作了分析;结果表明:在任丘~保唐~沧州一带仍存在着+60~+80×10_(-8)m/s_2的高值异常。并认为该异常主要由其深部变异因素引起,故应给予高度重视。
In this paper, the quasi-stationary adjustment treatent, ground water correction and ground deformation correction of the data of repeated gravity measurements around Renqiu-Baotang-Cangzhou area are made. Then the variation of gravity field appeared since 1986 is discussed. The results show that around this area exists a high value anomaly of+60~+80×10^(-8) m/s^2. It can be inferred that this anomaly is mainly caused by deep variations. Therefore, it is necessary to pay attentionto it.
