摘　　要：高速公路建设中会涉及诸多地质条件复杂的生态敏感区工程,为遵循经济和绿色环保的工程建设要求,本文通过对穿越环境敏感区的高速公路施工便道进行调查分析,研究了预制桩板式施工便道结构技术,该技术依靠钢管桩与土层的摩擦力作路基主要承重,增强钢管桩顶部与预制面板连接的可靠性,无须对路基进行处理,可直接在原状土上进行施工,对原状土的扰动较小。经过实践,结果显示该项技术可以重复利用,工后复垦简单,对施工便道所占田地以及周围土壤不造成污染,符合绿色环保的施工要求。Many projects in ecologically sensitive areas with complex geological conditions will be involved in the construction of expressways.In order to comply with the construction requirements of economic and green environmental protection,this paper investigates and analyzes the highway construction walkway that passes through the environmentally sensitive areas,and studies the construction technology of prefabricated pile-plate construction walkway,which relies on the friction force between steel pipe piles and soil layer as the main bearing capacity of the subgrade.The reliability of the connection between the top of the steel pipe pile and the prefabricated panel is enhanced,and the roadbed is not required to be treated,and the construction can be carried out directly on the undisturbed soil.Through practice,the results show that the technology can be reused,the reclamation after construction is simple,and the field occupied by the construction road and the surrounding soil are not polluted,which meets the construction requirements of green environmental protection.
