- Abstract:
-
The No. 8 water intake tower of Xiaolangdi was discretized by using the 21~1 node block unit, and the stress of the arc door section of the working door under the water retaining load was analyzed, and the internal force value of 10 sections and the stress state of the side wall of the lock chamber were calculated. The calculation results show that the bending moment obtained by the detailed calculation increases to different degrees in many places, while the axial force and shear force decrease to a considerable extent. There is a large tensile stress area on the inside of the side wall, the maximum value is 2.08 MPa, and it is recommended that the design unit take other engineering measures to solve the problem of bidirectional tensile stress in the large area of the side wall.
