摘要
基于云南省地质环境背景条件及公路网情况,搜集了51条高速公路弃渣场工程设计资料,通过统计研究弃渣场数量与线路里程、桥隧比、地形地貌等因素之间的关系,分析了云南山区公路弃渣场分布特征及其影响因素。结果显示:新建高速公路双向4车道平均每2.01 km设置1座弃渣场;新建双向6车道高速公路上,平均每1.59 km设置1座弃渣场;改扩建高速公路上,平均每25.78 km设置1座弃渣场。研究结果表明,新建高速公路桥梁占比、隧道占比与弃渣场数量没有直接关系,而改扩建高速公路桥梁占比、隧道占比与弃渣场数量呈正比,即桥梁占比、隧道占比越大,则弃渣场数量越多。
Based on the geological environment background conditions and highway network in Yunnan Province,this paper collects the engineering design data of 51 highway spoil areas,and analyzes the distribution characteristics and influencing factors of highway spoil areas in mountainous areas of Yunnan Province through statistical research on the relationship of the number of spoil areas and line mileage,bridge tunnel ratio,topography and other factors.The results show that the two-way four lane expressway is equipped with a spoil ground every 2.01 km,the new two-way six lane expressway is equipped with a spoil ground every 1.59 km,and the reconstructed expressway is equipped with a spoil ground every 25.78 km.The research results show that there is no direct relationship between the proportion of bridges and tunnels in newly built expressways and the number of spoil ground,while the proportion of bridges and tunnels in reconstructed expressways is directly proportional to the number of spoil ground,that is,the larger the proportion of bridges and tunnels,the more the number of spoil ground.
