Embodiment Construction

[0021] The arch dam full deformation monitoring instrument method of the present invention is, the different elevation L1, L2, L3, L4 of a certain section of the arch dam is provided with monitoring instrument in corridor 7 or observation room 6 in the dam, and described monitoring instrument comprises vertical Line monitor and tilt monitor 5, and one-to-one corresponding setting, the vertical line monitor is No. 1 vertical line monitor 1, No. 2 vertical line monitor 2, No. 3 vertical line monitor 3, and No. 4 vertical line monitor 4. Tilt Monitor 5 also has a corresponding number of settings, such as figure 1 shown. Through the monitoring results of the tilt monitoring instrument, the corresponding deformation of the upper dam body at the position of the monitoring point is calculated before the vertical line is installed, so as to correct the vertical line monitoring results of the arch dam segment, so as to obtain the actual full deformation of the arch dam. The setting of...

Abstract

The invention provides an arch dam complete-deformation monitoring method. The method is characterized in that monitoring instruments are arranged in galleries or observation chambers at different elevations of a certain section of an arch dam, wherein the monitoring instruments include a perpendicular monitoring instrument and an inclined monitoring instrument, and the perpendicular monitoring instrument and the inclined monitoring instrument are arranged on a one-to-one correspondence mode; by means of the monitoring result of the inclined monitoring instrument, deformation of an upper dam body at a monitoring point during the period that a perpendicular line is not installed is calculated, and accordingly a perpendicular line monitoring result of a segmented section of the arch dam is corrected, and actual complete-deformation of the arch dam is obtained. The method solves the problem that the actual complete-deformation of the arch dam cannot be monitored, is successfully used in water-power engineering, achieves a good effect and is good in practicability. The method changes safety monitoring design and monitoring methods of arch dams in China, and has wide market prospects and popularization value in the arch dams.

Description

technical field [0001] The invention relates to the technical field of hydropower engineering, in particular to a method for monitoring the total deformation of an arch dam. Background technique [0002] In recent years, my country's hydropower has developed particularly rapidly, such as the Xiaowan Arch Dam on the Lancang River (dam height 294.5m), the Jinsha River Xiluodu Arch Dam (dam height 285.5m), the Yalong River Jinping Class I Arch Dam (dam height 305m), and the Jinsha River Baihetan Arch Dam. A number of high arch dams represented by hydropower station arch dams (dam height 277m) have been built one after another, making my country's arch dam design theory and construction technology reach the international advanced level. However, the development of arch dam safety monitoring technology obviously lags behind the development of dam construction technology. With the continuous increase of the dam height, the influence of the inclination of the dam body and the dam ...
