热力工程中人孔盖板抗剪设计理论探讨

Discussion on manhole cover shear-resistant design theory in thermal engineering

通过对热力工程中人孔盖板荷载作用下各种受力情况的分析研究,指出采用分布角方法结合影响线理论对人孔盖板的抗剪承载力进行计算,得出了板端的最大剪力值,从而使人孔盖板的抗剪设计更加合理。

Through the analysis and research on various stress condition of manhole cover shear-resistant design theory in thermal engineering, this paper pointed out that using angular distribution method combining with the influence line principle calculated the shear-resistant bearing ca- pacity of manhole cover, gained the maximum shear value of plate end, so that the shear-resistant design of manhole cover more reasonable.
