Watching lock chambers gateway number 30 and number 31 of the Volgograd hydroelectric during the operation showed that the main parameters to be controlled are the piezometric levels of groundwater in fillings chambers values pressure on the bottom of the camera, the concrete situation and the movement of the top wall chambers under different operating loads. Measuring movement of the top of the wall is the most problematic in the existing now in the current monitoring system of hydroelectric — available means of geodetic measurement of dynamic deformations of the walls of the cameras is almost impossible. Ongoing measurement facilities allow only finite values of relative displacement chamber walls during the filling-emptying. To determine the independent movement of each element in the process of changing the water level in the chamber is not possible by existing methods. Processes occurring in the locking of vessels, rather dynamic, the duration of the passage of the ship through the gateway are within 40 – 60 minutes. During this time the chamber is filled, and its walls are deflected in the direction of filling, then in the process of emptying the chamber top wall is moved in the axis of the chamber. The deviation depends on the design of the walls, the nature of backfill soil, the groundwater level in the filling, and other factors. The dynamics of these processes (the movement speed and amplitude) affect the stability con constructions gateway and magnitude of the stresses arising in them, which in turn determines the operational safety of locking processes. Performed on shipping Volgograd hydroelectric plants pilot project on the measurement of displacements structures using Total Station has demonstrated the ability to produce a whole range of information about the movements of structural elements. Analysis of such information creates the possibility of a more objective assessment of the state of the ship lock.
