- Abstract
The integral lock chamber with unloading plate can reduce the inner force and displacement of the lock chamber and increase the anti-floating capacity. As a new type of hydraulic structure, it is firstly applied to Nanping Navigation Lock Project in Huihe River. In order to further reveal the mechanical and deformation characteristics of integral gate chamber structure with unloading plate under backfilling load, the variation law of earth pressure, pore water pressure and deformation of sluice wall with time during backfilling construction was analyzed by field monitoring and numerical simulation. Compared with the traditional dock type lock chamber structure, the earth pressure and effective force of the integral lock chamber structure with unloading plate are reduced significantly, the unloading effect is obvious, the deformation of the lock chamber structure is effectively controlled and the new structure has improved the safety and stability of the ship lock.
