Evaluation Of The Natural Disaster Slope Protection Models About Freeway From Baotou To Dengkou Section In Inner Mongolia

Since the expressway construction will inevitablely bring about the difference between the side slopes along the highway on both sides and the original vegetation, soil, geology and general configuration of the earth's surface, the side-slop-protection in expressway construction, including the realization of embellishment, transportation and ecological protection, the high way as the gallery and the cut and roadbed side slope as the green belt, is of great importance, to insure the smoothness of transportation and the improvement of ecology on both sides.Contemporary highway side slope protection synthesizes the mechanical engineering, bioengineering and ecological project, to emphasize especially the ecological functionality. There are no relevant reports concerning about how these protect pattern and comprehensiveness embodies in highway side slope protection effect, how important it is, how each pattern contribute to the side slope protection, and what should be taken into consideration.On the basis of expressway project from Baotou to Dengkou Section, this thesis mainly introduced the protection pattern against natural disasters and the method of evaluation, analysed and studied the various types of protection which including sand-protection from the source,flood-protection,mud-rock-flow-protection and snow-protection and so on, and finally recommend the best protection model according to different investigations and AHP.Analytical results indicated that from middle in Inner Mongolia turban to thudding, among various slope protection measures, the biological protection pattern and engineering combine together is the best pattern in soil and water conservation side slope protects; While in the wind-corroded desertification, biological protection is the best pattern among side slope protects patterns; While in snow-destroyed side slope, engineering protection pattern is the best; The side slope protects with living things and machinery protects synthetically flood and the mud-rock flow which is the best protection pattern; the biological protection pattern and engineering combine together is the best pattern collapse side slope protects。...
