近年世界各国开展地下水微动态研究,我国现已建成近300眼观测井,观测精度达毫米,能跟踪由于荷载效应和新构造运动孕育的地震效应所引起的超孔隙水压力的畸形 In recent years, various countries in the world have conducted groundwater micro-dynamic studies. As a result, nearly 300 observation wells have been built in our country and the observation accuracy is up to a few millimeters. Therefore, the deformability of excess pore-water pressure caused by the earthquake effect in the new tectonic movement can be tracked
