Description

Device and method for early warning of landslide surge disaster on reservoir bank of large reservoir
Technical Field
The invention relates to the field of surge disaster early warning, in particular to a large reservoir bank landslide surge disaster early warning device and method.
Background
The mountainous areas in southwest of China have large topography drop, rich water energy resources, develop and build a plurality of large hydropower stations, and form a plurality of high dam vaults. Due to complex geological environment in southwest mountain areas, strong geological structure movement, frequent mountain geological disasters such as landslide and collapse, if a reservoir area bank slope is subjected to rapid unsteady damage, a large amount of rock and soil bodies can form swells with wave heights of tens meters and even hundreds of meters after entering the river rapidly, the propagation distance of the swells along the river can reach several kilometers to tens kilometers, the ships along the way can be lifted during propagation, the coastal infrastructure is damaged, personnel casualties are caused by involving a bank movable person into the river, and even urban towns on the downstream coast can be destroyed by turning over a dam. Therefore, the method has the advantages of early warning on the surge disaster, reducing property loss and casualties, and having great social practical significance.
The cause of the surge disaster is a reservoir bank landslide, at present, prediction and early warning of the landslide is still a worldwide problem, although scientists propose a plurality of landslide prediction and early warning methods, most cases of successful early warning and emergency relocation avoidance are decided by means of group detection group anti-discovery landslide deformation signs and expert judgment, few cases of abnormal deformation and successful early warning are found through an automatic monitoring instrument, and only landslide bodies with simple part of geological conditions, small scale, abundant basic investigation data, more monitoring instruments are buried and higher research degree are reported. In a high dam large warehouse with a shoreline as long as hundreds of kilometers, detailed geological investigation and monitoring work are difficult to be carried out on all the shores, part of high-level shoreside manpower is extremely difficult to reach, and landslide hidden danger is difficult to discover in time, so that the method for early warning the surge disaster through landslide early warning is difficult to popularize and apply in a large reservoir. The early warning device and method specially aiming at the surge disaster are rarely reported, and the current disaster risk prevention and control needs are difficult to meet.
The reservoir bank landslide surge disaster is characterized in that the water level changes greatly in a short time, the position and the scale of the surge disaster can be found by monitoring the change of the water level along the reservoir bank, and then an early warning signal can be issued. Therefore, the key of the surge early warning is to quickly, accurately and continuously obtain the reservoir water level change information.
At present, a pressure type water level gauge or a radar water level gauge is generally adopted for measuring the water level of a reservoir, the principle of the pressure type water level gauge is that the distance between the position of a sensor and the water surface is calculated according to the water pressure received by the sensor, the sensor needs to be fixedly buried below the dead water level of the reservoir for a certain distance, the underwater condition is complex, the instrument maintenance operation is inconvenient, and when an underwater bank slope is unstable, the position of the instrument changes, and the reading error is possibly caused. The measuring principle of the radar water level gauge is that a radar water level sensing antenna arranged on the shore above the water surface transmits radar pulses and receives water surface reflection pulses, and the distance from a river channel to the water surface is calculated according to the time of transmitting the received signals. In general, the radar antenna needs to be erected from the shore to measure the upright posts and is arranged perpendicular to the water surface on the transverse rods transversely extending to the water surface, and for a high dam, the water level amplitude between the normal water storage level and the dead water level can reach tens of meters, the length of the transverse rods required by arranging the radar water level gauge is too long, the installation difficulty is high, the structural stability of the upright posts is difficult to ensure, the measuring range of the radar water level gauge is limited, the requirement of the high dam, the water level measurement of the high dam is difficult to meet, and the problems of Chinese patent No. CN211696584 'a water level early warning and monitoring device', and Chinese patent No. CN212007423 'a reservoir water level detection device' all exist. Chinese patent CN111623853 'a laser measuring device for measuring reservoir water level and a measuring method thereof' adopts a mode of arranging a water level gauge target disc on the water surface of a reservoir and arranging an infrared ranging tracking head on a control tower on the bank to measure the reservoir water level, wherein the water level gauge target disc is fixedly anchored on the water surface of the reservoir, so that the shipping safety is easily influenced; when the surge occurs, the target disc can be submerged by the water level surge, and the target disc is dragged away from the original position, so that data cannot be continuously read, and the method is difficult to be applied to emergency early warning of the reservoir landslide surge. The Chinese patent CN112652148A system comprises a surge induction unit, a surge identification unit and a surge early warning unit, wherein a water level sensor of the surge induction unit is arranged on a pile foundation, the pile foundation is respectively arranged on the upstream side of a landslide, the downstream side of the landslide and the opposite side of the landslide, the surge induction unit is used for monitoring surge height information of the position where the induction pile foundation is located, the surge identification unit is used for receiving the surge height information transmitted by the surge induction unit, distinguishing disastrous surges and calculating and analyzing to obtain surge early warning information, and the surge early warning unit is used for receiving the surge early warning information transmitted by the surge identification unit and carrying out early warning. The water level sensor metering method is fuzzy, and false detection is easy to form, so that the final effect is poor.
