Laser rangefinder monitoring of hydro-technical utilities position (the case of Ust-Kamenogorsk shipping lock)
The description of the laser rangefinder monitoring system for Ust-Kamenogorsk shipping lock's wall deflections and the results of 8.5-years observations are presented. Ust-Kamenogorsk shipping lock has high-head single-lift chamber with 47 m depth. The wall deflections are caused by seasonal thermal deformations and dynamic loads related to the lock filling-emptying. The trend is found of the chamber width decrease with the rate of ~ 2.2 mm/year in the upper part of the lock. The effect of the lock filling-emptying process on the wall deflection dynamics was studied.
