Ma Gold Shop To The Chengjiang A Highway Engineering Economic Feasibility Studies And Social Argument

In the light of the fact of national development and Yunnan governmental traffic construction "major net: 3 horizontals and 3 verticals — 9 passageways". It will push traffic construction to a new stage in Yunnan. In order to get the better effect of major passageways, some connect ways among them are necessary. They will provide more convenience among the major passageways. The old road from Majinpu to Chengjiang is the quickest road from Kunming through Chengjiang, Huaning to Jianshui. The conclusion that this road's traffic volume will increase in the future can be made from the traffic volume analysis and the forecast. The old road can't adapt to the needs of increasing traffic volume. Tourism and economic development in Chengjiang are seriously restricted. The technical level increase of the road will improve social economic development in Yuxi city, and it is important to develop tourism in Yunnan and speed up transform of traffic net in Yunnan province. The transform is urgent.The study about Ma—Cheng one level highway's engineering feasibility and social economic returns in the thesis divided into 4 parts. 1. Volume of traffic and social economic returns forecasting. Traffic volume was forecasted through the analysis of present traffic situation of Ma—Cheng Road. Social economic returns were forecasted through developing tendency of the road district. 2. construction planning: construction condition, scale, technical standards. 3. Investment estimation and economic evaluation. Only national economic evaluation was made in this thesis. 4. Environmental impact analysis. The steps of environmental protection to water, atmosphere and wild animals were proposed. Above all, Ma—Cheng one level highway is feasible and it has good social economic returns.
