Estimation of the fatigue life of lock-gate elements of the Moscow Canal

Hydrotechnical Construction Aims and scope

Conclusion

The investigation and estimation of the life of lock-gate elements shows that for the adopted design and technology of manufacturing lock gates a sufficiently high fatigue life cannot be provided without intermediate repairs.

It is necessary to develop design and technological measures to reduce the level of maximum cyclic stresses and strains in the structure and also to use materials, types of welds, and methods of rapairing lock-gate elements which increase the characteristics of fatigue strength. In this case, for example, a decrease of the maximum cyclic strains in the weld zone of the gates to 0.175–0.2% (which is possible by means of design and technological measures and reduction of the level of stress concentration) will make it possible to increase the life of the gate elements and to increase the period between repairs to 10–15 years, which should be considered completely satisfactory for operating practice.
