摘要
近年来,随着我国经济高速发展,交通建设规模空前,全国高速路网逐步完善,近期高速公路建设多集中于欠发达的山区,而山区高速公路建设,需克服山高坡陡、地形蜿蜒、地质灾害频发的困难,为节约公路造价,保护生态,少占耕地、林地,山区高速公路多采用随山就势,半挖半填路段较多,遇山体陡峭路段,施工难度大且公路安全稳定性差,抵抗地质灾害能力差,经笔者研究发现,在山区高速公路建设中,在半挖半填及滑坡地段,采用泡沫轻质土,可少设结构物减少山体破坏,节约工程造价,减轻公路自重增加搞灾能力,值得推广,下面以工程应用实例进行分析。
In recent years,with the rapid development of China's economy,the unprecedented scale of traffic construction,and the gradual improvement of the national highway network,the recent highway construction is mostly concentrated in underdeveloped mountainous areas.However,the highway construction in mountainous areas needs to overcome the difficulties of high mountains and steep slopes,winding terrain and frequent geological disasters.In order to save highway costs,protect the ecology,and occupy less arable land and forest land,the highway in mountainous areas is mostly built along the mountain,and there are many sections of half excavation and half filling.In case of steep mountain sections,the construction is difficult,the road safety and stability are poor,and the ability to resist geological disasters is poor.The author has found that in the construction of expressway in mountainous areas,the use of foam light soil in half excavation and half filling and landslide sections can reduce the number of structures,reduce the mountain damage,save the project cost,reduce the self weight of the road and increase the disaster capacity,which is worth popularizing.The following is an example of engineering application for analysis.
