交通荷载作用下高填方涵洞动力响应研究
Analysis of Dynamic Response of High Embankment Culverts under Traffic Loads
摘要
Abstract
A numerical model of arch culvert was established and the process of installation of the culvert and construction of the embankment were simulated.Then the traffic loads were applied on vertical section of the road,and parametric studies were carried out to investigate the influence of cycle times,traffic loads and vehicle speeds on the dynamic responses of arch culvert.The results show that the arch is the most vulnerable component of the whole culvert under traffic loads.After eight times cycle of traffic loads,the settlement of road surface and the vertical earth pressure on the top of culvert tends to be stable.The vertical earth pressure at the top of culvert increases as the traffic loads increase.The vertical earth pressures both at the top and bottom of culverts are not sensitive to the variations of the vehicle speeds.关键词
