Research On Strengthen Of Carrying Capacity For Mountain Railway

Railway was the important constituent of transportation system in our country. As the developing of society and economic in China, especially under the condition that our country socialist market economy is continuously developing, standard of living is improving for people day by day, and need for Transport market is increasing constantly. Railway construction can not reach the need of demand growth, mountain area above all. In order to fit requirement of socialist market economy development, we have adequate capacity as guarantee, expanding transport capacity, increasing economic efficiency and social benefitBased on the current situation and characteristics of mountain railway in our country, this thesis studys many ways of improving the carrying capacity, analyzs factors that effecting and restricting the trafficability and gives quantitative analysis for them. It expounds the lacks of transportation facilities for mountain railway and find out spare links of mountain railway to seek suitable method which can rais carrying capacity effectively.Than, some methods of improving trafficability are studied, mainly from two fields that improving the quality of traction and rate of traffic flow, enhancing the rate of traffic flow focused on using the single track automatic block system primarily. A detailed analysis is given which is of feasibility and space of improving the quality of traction under the mountain railway special conditions, as well as influence of single track automatic block on line capacity, train stations and travel speed. Then, using method of weight analysis on a variety of methods to quantify the comparison, we can get the rank ordering of quality for them under specific conditions, as well as the sort of compatibility with each other.Finally, taking the DaRui line for example, the article analyzes the methods of increase the capacity used in the new line, proves feasibility and necessity of them and Attempts to provide theoretical references for new line and expanding and rebuilding capability of mountain railway in the future.
