摘要
从动态的观点介绍了大地水准面的物理意义。用数值分析方法计算了常见的几种断层位错导致的大地水准面局部变化的分布图像 ,并着重研究了断层位错的倾角与大地水准面变化之间的关系。另外 ,还研究了扩容引起的大地水准面的变化 ,最后讨论了利用海洋验潮资料和卫星测高以及雷达测高资料监测海域及海洋沿岸孕震区局部大地水准面的可能性 。
The physical sense of dynamical geoid is discussed and the patterns of local geoid changes due to several faulting dislocations are studied by using the numerical analysis method.The relation between fault dislocations and geoid changes is emphatically stud- ied.Moreover,the geoid changes caused by dilatancy are also studied.Atlast,the possi- bility to monitor local geoid changes of seismogenic zone in the fields of sea and seashores by means of tide-gauge observation,satellite altimetry and radar altimetry is deeply dis- cussed and it is thoughtthat the means is of very impotent significance in monitoring and predicting earthquakes.
