Monitoring Method of Dam Body Deformation of High Rockfill Dam

Abstract

The invention relates to a high rockfill dam body deformation monitoring method. The method comprises the steps of: connecting an array displacement meter with deformation monitoring robots, wherein each monitoring robot forms a monitoring unit, and the deformation monitoring robots are connected with a data processing platform through wireless transmission, and the plurality of monitoring units are connected in order to form monitoring assemblies; selecting a plurality of horizontally-arranged surfaces in the height direction of a dam body, arranging first monitoring assemblies parallel to the downstream direction of the river and second monitoring assemblies parallel to the width direction of the river on the horizontally-arranged surfaces, and then arranging a plurality of sets of thirdmonitoring assemblies at intervals are arranged in the vertical direction; and receiving formation information at each monitoring point by the data processing platform, performing calculation according to the received deformation information of each monitoring point to obtain deformation quantities in the downstream direction of the river, the transverse direction of the river and the vertical direction by the data processing platform, and displaying the obtained deformation quantities in each direction to a user. The method is simple in operation, detailed in obtained data, free of maintenance for a long time and wide in application range.

Description

technical field [0001] The invention relates to the technical field of dam monitoring research, in particular to a method for monitoring deformation of a high rockfill dam body. Background technique [0002] Dam safety monitoring is an effective means for people to understand the dam's operating status and safety status, and it is also one of the important measures to ensure its safe operation. Dam safety inspection is to understand the working behavior of the dam by obtaining first-hand information in time, and provide a basis for evaluating the condition of the dam and abnormal phenomena, so that appropriate plans and maintenance measures for the dam can be formulated to ensure the safety of major projects. safe operation. Dam displacement monitoring can be carried out in two ways, manual and automatic. Most of the traditional dam safety monitoring is manual measurement. On the one hand, it is easy to cause inaccurate data and poor monitoring accuracy due to human error;...

AI Technical Summary

Problems solved by technology

Traditional dam safety monitoring mostly uses manual measurement. On the one hand, it is easy to cause inaccurate data and poor monitoring accuracy due to human error; on the other hand, it will increase the labor intensity of the staff.

However, the current automatic wired distributed system has many disadvantages in the monitoring system, such as more interference, easy damage, high cost, and difficult installation and maintenance.
