岫岩深井地处辽东半岛中部大洋河断裂与苏子沟、向荣断裂的交汇处。井深250米,含水层厚度67米(183—250米)。属元古代花岗岩裂隙承压水。该井于1975年10月开始观测,从1977年8月起用“红旗-1”型水位自记仪观测至今。 由于地球固体潮汐作用,深井水位具有同固体潮相同的变化特征(图1a)。图1a为水位 Xiuyan deep well is located in Liaodong Peninsula, the central Pacific Ocean fault and Suzigou, Xiangrong fault intersection. Well depth of 250 meters, aquifer thickness of 67 meters (183-250 meters). Is a metamorphic granite fracture pressure water. The well began observing in October 1975 and has been observing so far since August 1977 using the “red flag-1” water level recorder. Due to the Earth’s solid tidal effect, deep well water level has the same variation characteristics as solid tide (Figure 1a). Figure 1a shows the water level
