The Research Of Tibetan Areas Of Roadbed Comprehensive Influence And Ecological Maintenance Technology

Most of our harassment by the sand area highway is mainly distributed in the desert region of xinjiang, if be located in the heart of the taklamakan desert oil highway, across the tengery desert "ningxia defender to Mongolia road", from the "edge through maowusu sandy land in shanxi province to Mongolia road" yulin. In these large area repaired the road, already accumulated part windbreak and interrelation of sand branch resection. But in many desert plateau area the harm of sand for highway remains, based on a highway in Tibet as an example, this paper discusses the overall harm of highway sand, and draw the ecological maintenance policy.This paper, on the one hand, in the implementation of the existing research results fully absorb, collect and analyze the existing engineering examples, on the other hand in Tibet, a highway characteristics of the existing research with little or no very clear content by inside and outside the combined entity engineering, tests and testing, theoretical studies methods of research. General study condition:material inquires various sub project literature survey-preliminary investigation on the site test research program-site formed a detailed survey and testing, establishing the theoretical analysis method in trials field engineering applied, physical test and inspection indoor theoretical analysis-write research report. The research in this paper that the main research results:Firstly, based on a sand along the roads in Tibet has investigated the basic research, and also the example related data gathering, and in the overall geology, to along the water lines and related sandstorm distribution and ecological environment on the basis of the analysis of the survey results, and puts forward the highway across the possible sand type and specific distribution, and for the suggested ecological maintenance type prevention schemes are relevant evaluation.Secondly, in the highway vegetation control based on the theory of sand along the roads, and summarizes the basic principles of sand prevention, and according to the concrete expressway in Tibet ecological environment purposefully presents specific choice for ecological protection of vegetation, and according to the specific conditions related, puts forward the ecological maintenance technology along highway the concrete implementation plan and requirements.After the actual research and to benefit assessment found along the road, on the ecological integrity of highway sand prevention maintenance plays an important role.
