| Abstract: | According to the principle of united pipe, united several points by using punctuate measuring system and pressure biography ,numeralic mode changing technologic by automatic measuring including land subsidence and groundwater level has been put into effect. Uniting network will realize measuring at the same time. Network managing, measureing data join to the land subsidence information managing system. To realize each measuring data (water amount , water level, base point and each layer compression ) and so on, information analysis has provided new method for studying control land subsidence. |
