- Abstract:
- Based on finite element analysis,considering three working conditions: 1 ) single wheel in the mid-dle of the manhole cover, 2 ) single wheel at the junction of the manhole cover and the road,3 ) single wheelx meters distance from the junction of the manhole cover and the road,it carried out the comparisons and anal-ysis of stress and deformation of the new type self-adjustable lifting manhole cover and the traditional manholecover on asphalt concrete pavement. The result showed that the vertical deformation and the wheel stress of thenew type manhole cover are less than the traditional one in the three working conditions,and the new typemanhole cover can be better compatibly deformed than the traditional manhole cover,reducing the relative de-struction of the manhole cover and the surrounding road.The research results of this paper provides theory ba-sis for the popularization and application of the self-adjustable lifting manhole cover.
