研究目的：新建客货共线铁路速度目标值标准选择不仅要考虑时间目标值要求,还应考虑客货共线运营的特殊性所形成的速差对其的影响。限制坡度标准对线路的走向、长度、工程投资、运营费用、牵引质量及输送能力,都有较大影响。
研究结论:本项目采用200 km /h速度目标值即能较好满足时间目标值的要求,与路网内的胶济客运专线、青荣城际、连盐线的速度目标值相协调。限制坡度采用6j满足本线能力需要,与路网相邻线路匹配良好。
Research purposes: To determine the speed targetvalue ofnew railway line formixed passenger and freight traffic should not only consider the demand of speed target value, but also should consider the influence of time difference caused by the feature of the line. The limit slope standard much affects the line trend, line length,construction investmen,t operating costs, traction quality and traffic capacity.
Research conclusions:The speed targetvalue of200 km /h used for this railway line canwellmeet the requirementsof the time targetvalue and coordinatewith the speed targetvaluesofJinan-QingdaoPassengerDedicated Line, Qingdao-Rongcheng Intercity Line, Lianyungang -Yancheng Line. The limit6jslope on this line can meet the demand of traffic capacity of this line andwellmatch the adjacent railway line in network.
