七十年代修建的水闸,有些平面闸门的行走支承部分采用滑块式支承和磁砖滑道。经过一个阶段的使用,陆续发生磁砖断裂与脱落现象,影响闸门的正常启闭,武障河闸的磁砖滑道也发生同样现象。为了分析磁砖滑道的损坏原因,我们对滑道的受力情况进行了计算和试验,并在此基础上对武障河闸磁砖滑道进行了改建。一、磁砖滑道的损坏原因分析目前磁砖滑道的破坏,主要是脱落和断裂,为分析原因进行了受力试验,并对压应力和剪应力进行验算。以武障河闸为 Sluice built in the seventies, some of the flat gate of the moving support part of the slider-type support and tile slide. After a period of use, one after another occurred in the phenomenon of tile fracture and shedding, affecting the normal opening and closing of the gate, Wu barrier barrier slide also occurred the same phenomenon. In order to analyze the reason of the damage of the tile slideway, we calculated and tested the force of the slideway, and on this basis we rebuilt the tile slideway of the barrier. First, the analysis of the reasons for the damage of the tile slide The current failure of the tile slide, the main fall off and fracture, for the analysis of the reasons for the force test, and the compressive stress and shear stress checking. Take Wu barrier river for
