某导流洞闸室门槽结构截面承载力分析

Analysis on Bearing Capacity of Slot Structural Section of Gate Chamber of Diversion Tunnel

随着平板闸门挡水水头的增加,闸门门槽受力越来越大,但是门槽的斜截面承载力计算规范中并未给出具体的计算方法,致使工程设计缺乏依据。以某水电站导流洞闸室门槽为例,首先采用ANSYS软件对闸门门槽结构进行了应力计算,其次对门槽的局部受压及斜截面承载力进行计算,通过计算得出闸门门槽结构满足设计要求。

With increase of water head to be retained by flat gate, action on the gate slot increases accordingly. But the specific calculation method for the beating capacity of the inclined section of the gate slot is not available in the code so that no basis on the engineering design can be relied one. With the case of gate slot of the gate chamber of one diversion tunnel, the stress of the gate structure is calculated by application of ANSYS software. Then, the local pressure of the gate slot and the bearing capacity of the inclined section are calculated respec- tively. These calculations prove the structure of the gate slot satisfy design requirements.
