利用CORS站网监测三峡地区环境负荷引起的地壳形变与重力场时空变化
|
Abstract:
受地球动力学因素特别是地球表层大气、地表水及地下水动力环境影响，地面站点位置、地球重力场及大地水准面随时间变化。以三峡地区CORS站网为主，少量重力台站为辅，采用负荷形变与地球重力场严密组合方法，综合确定了2011-01-2015-06三峡地区环境负荷驱动的地壳形变与重力场月变化，结果显示：（1）CORS站网具备地壳垂直形变、大地水准面及地面重力变化的监测能力；（2）三峡地区地壳垂直形变年变化幅度36.1 mm，大地水准面年变化幅度28.2 mm，地面重力年变化幅度117.4 μGal；（3）CORS站网地面重力变化监测精度水平不低于流动重力场重复测量；（4）CORS站网地壳垂直形变与地面重力变化监测具有一定的外推预报能力
