Research And Application Of Automatic Monitoring System In Landslide Monitoring In Reservoir Area Of Water Power Station

The water resources in southwest China are rich,and thousands of different types of hydropower stations have been built and constructed.Due to the large uplift of the groundwater level in the reservoir area,the reservoir area of the hydropower station often forms a landslide,which is one of the potential hazards of the safe operation of the power station.The main measures of landslide disaster prevention are the safety monitoring of scientific system,timely management and early warning.With the continuous progress of science and technology,the method of landslide safety monitoring evolves from the original data acquisition and processing automation monitoring system of the data processing in the external industry.The automatic monitoring system,which usually includes the data collection,the network sending and storing of data,the data automatic processing analysis,the early warning alarm automatic sending and so on,is an effective landslide safety monitoring technology.Based on the study of the major landslide safety monitoring techniques at home and abroad,this paper designs and implements the automatic safety monitoring system of the landslide body according to the geological report of Tianba Village landslide in the reservoir area of Yunnan ceiling hydropower station.Implementation of the project in accordance with the "Geological conditions of engineering areas--Safety monitoring Program design--On-site equipment installation and commissioning--data processing center installed and debugging," the step-by-step scientific implementation.The safety monitoring system designed by the field data acquisition equipment,network data transmission media and security Monitoring data processing Center three parts,the surface displacement,deep displacement,groundwater level and reservoir area water level and other data of automatic acquisition and processing analysis,in the landslide occurs when the large changes in the timely warning,Guarantee the safe operation of the dam of power station Reservoir.During the 2013-2016 year continuous monitoring period,the system runs stably,the data is abundant and reliable,the processing analysis is scientific and reasonable,and the real-time monitoring of the landslide before and after the "8 3 Ludian Earthquake" in 2014 is not interrupted,and the timely early warning information is released before the earthquake,which provides a powerful data support for the rescue and relief during the earthquake.It is proved that the system is scientific and effective,and has a certain representativeness.
