Design Idea And Practice Research Of Highway Route In Gansu Province

The fast development of highway traffic and the western mountainous road which proposed higher require to highway design, construction, management and maintenance technology, the rationality of the road selecting-route is one of most important questions.The route program's choice is the important work that decides the overall situation in the road survey design. Not only the condition of road position is affected by terrain, geology and ecology environment, moreover when the road was constructed, it is reaction to the nature and will carry on the more or less destruction to the natural terrain, the ecology and so on, and simultaneously the route position have the profound influence to the road safety-operation. In view of Gansu province mountainous area road characteristic, and based on the road route selection characteristic, the principle and the step, the route reasonable plan choice carries on the analysis and research key to fills in high deep cuts, the steep slope and the river valley approaches the mountain land sector, in the special unfavorable geological land, and proposed the concrete principle and technical plan to the steep slope land sector, the river valley approached the mountain land sector, and carry on the induction summary to roadbed structural arrangement form and the adaptation condition.The analysis the domestic and foreign conceptual design development situation, integrating the development of the Gansu Province highway conceptual design at present, and in view of the actual situation of our province, proposes the environment selecting-route, the security selecting-route and so on, the various factor coordinated processing, and the Baoji to Tianshui the highway application.In view of the peculiar circumstance of accomplished construction documents design in Hezheng to Hezuo by myself, flexibly utilizes the technical specification, boldly innovate, and make the research in the security, the optimal design, the environmental protection and humanist aspects. The project was analyzed and summarized in according to the conceptual design, and made the optimal design to the unreasonable land section.
