| 摘 要： | 利用四川地区GNSS观测数据研究该地区季节性负荷位移场及季节性负荷应力应变场，并结合降水数据分析该地区季节性水文负荷对地壳变形及活动断裂带附近应力应变的影响。结果表明，四川地区地表发生的季节性位移与降水之间存在很强的时空相关性；水文负荷周期性变化产生的负荷应力扰动对活动断裂带的应力积累模式具有一定的调节作用，进而影响活动断裂带的运动状态。

| Abstract: | We use GNSS measurements from Sichuan province to analyze the seasonal load displacement and stress-strain field. Combined with precipitation data, the effect of seasonal hydrological load on crustal deformation and stress-strain near active faults in this region are analyzed. The results show that there is a strong spatio-temporal correlation between the seasonal surface displacement and precipitation in Sichuan. The stress disturbance caused by the periodic change of hydrological load has a certain regulating effect on the stress accumulation mode of the active fault zone, which then affects the motion state of the active fault zone. |
