Abstract:

In the design of triangle gate lock head, the longitudinal internal force of the soleplate is not calculated regularly. In addition, the transverse internal force of side pier and soleplate is calculated separately by Guo's table method, which doesn't consider the fact that the side pier in the gate recess segment is thinner, inconforming with. practical condition, so the result is not accurate. In order to improve the lock head structure design, two simplified methods were put forward to check the longitudinal internal force of soleplate inside the gate chamber, and the finite element software was used for calculation and comparison. The analysis result show that in the transverse direction, the bending moment of front segment calculated by Guo's table method is smaller, and the bending moment of gate recess segment and the back segment is larger, so the internal force should be adjusted many times. In longitudinal direction, the calculation results of the simplified methods and finite element method are close.
