重型汽车下河斜坡码头合理纵坡研究

从车、船两方面因素对重型汽车下河斜坡码头合理坡度进行研究。以常见重型自卸汽车及一般内河船型为研究对象，重点分析汽车爬坡能力、下坡能力及码头前沿设计水深对坡度的约束。结果表明，码头斜坡道合理的坡度范围约在5.5%～9%，且汽车总质量越大，船舶吃水越深，下河斜坡道坡度可选择的范围就越小，甚至趋于一个定值；同时斜坡坡长不宜超过150 m，且车速宜控制在10 km/h以内。

Reasonable slope on sloping wharf for heavily loaded truck

This paper analyzes the reasonable slope for heavily loaded truck from two aspects, i.e. truck and ship respectively. Taking common heavy dump truck and general river ship as the research object, this paper analyzes emphatically the value of slope limited by climbing ability, downhill performance and design water depth.The results show that the range of reasonable slope is from 5.5% to 9%. The greater the truck weight, and the deeper the ship draft, the less range of choice on the rive slope, which even tends to a fixed value. Meanwhile, the length of the slope should be no more than 150m,and the speed of the vehicle should be controlled within 10km/h.
