Study On Ecological Engineering Design And Construction Of Guizhou Second-class Reconstructed Highway

Taking the reconstruction of Kaili-Leishan second-class highway of Guizhou province as the engineering background, This paper mianly studied on the coordination between the ecological environment and road alignment, road foundation, road protection, road drainage system and road affiliated facilities. The ecolgoical landscape restorationand design were studied,Combined with the weather, geohydrology condition,geologic feature,vegetation coverage and plant population, human construction behavior, local humanities tradition.This paper analysed the following aspects about road design and construction technology:critical technology study on road alignment in harmony with ecolgoical landscape design, study on road subgrade drainage and road protection and road facilities in harmony with ecological environment design, study on road structure and road affiliated facilities in harmony with ecolgoical landscape restorationand design, sudy on road slope in harmony with ecolgoical landscape restorationand and design.By the intensive analysis, this paper conluded the following innovative aspects: road alignment indictor and alignments conbination design approach, road subgrade drainage and road proction typical form, road stucture and affiliated facilities ecolgoical landscape restorationand design approach, road slope ecolgoical restoration and landscape design approach.This road reconstruction engineering was implemented as the Guizhou ecolgoical demonstration project. Conbined the roadside historical and culrual heritage, local condition and customs and natural scenery with the road design, it was constructed as the ecolgoical landscape road integrated the transportation and travel and humanities tradition. This study conclusion may will be adopted in the project implemention and provides the experiences to similar projets, simultaneously, it can be refered by the same industry engineers.
