Problems solved by technology

[0003] Dams are often built in remote mountainous areas, and the transportation and living environment are extremely inconvenient. It is not very convenient to manually inspect continuously or send special personnel to monitor, and there are the following disadvantages: currently, the dam settlement is measured in the deformation monitoring of the reservoir dam, It still mainly relies on manual measurement. The most widely used geometric leveling method for vertical displacement monitoring is periodic leveling by manual leveling. Although the measurement accuracy is high, there are heavy workload, low observation efficiency and long observation period. , greatly affected by the external environment, unable to realize many inconveniences such as automation

Abstract

The invention discloses a dam displacement monitoring method, which is characterized in that laser emitted by a laser emission module is irradiated on a coding target screen, an imaging module acquires an image on the coding target screen and transmits the image to a data processing unit, and the data processing unit receives the image, reads the code of the position of the laser on the image, carries out data analysis on the code, identifies to obtain the coordinate data of the position of the laser, and judges whether the dam has a displacement phenomenon according to the coordinate data. According to the invention, the settlement of the dam body can be automatically and accurately measured, and the method is small in manual operation workload, high in measurement speed, high in efficiency and small in external environment.

Description

technical field [0001] The invention relates to the technical field of dam safety in water conservancy and hydropower projects, and more precisely relates to a dam displacement monitoring method. Background technique [0002] Under the complex geological environment, the interaction mechanism between the dam and the foundation geological body is very complicated, and the overall stability of the foundation geological system of the dam is affected by many factors and different failure modes. The overall stability of the dam has always been the focus of attention in water conservancy and hydropower projects. It is related to the safety of people's lives and property and the construction of the national economy. The dam building is developing discontinuous structural planes such as weak interlayers, cracks, faults and other intercut dam foundation rocks. When there is an unfavorable combination of weak structural surfaces, its stability will be controlled by the weak structural...
