摘要
由于我国山区众多,大面积国土地处山区,受到地形地貌的影响,半填半挖路基是进行山区公路建设中不可避免的一种路基形式,能够充分利用挖方岩土,在生态保护方面有重要的作用。但是,由于在施工期间填挖路基搭接处理不到位,导致公路在运营期间容易成为病害重灾区,严重影响公路的质量以及使用寿命。论文通过对填挖交界路基病害的形成机理及影响因素进行研究,并进行分类,对其施工阶段以及运营阶段的处治方案进行了分析,为填挖交界路基病害的处置提供参考与建议。
Due to the numerous mountainous areas in China,a large area of the country is located in the mountainous areas,which is affected by the topography and landform.It is an inevitable roadbed form to semi-fill and half-dig the roadbed in the mountainous area highway construction.It can make full use of excavated rock and soil and plays an important role in ecological protection.However,due to the inadequate treatment of filling and digging roadbed during the construction period,it is easy for the highway to become the worst-affected area during the operation period,which seriously affects the quality and service life of the highway.By studying the formation mechanism and influencing factors of roadbed diseases at the junction of filling and digging,and classifying them,this paper studies the treatment scheme at the construction stage and operation stage,which can provide reference and suggestions for the disposal of roadbed diseases at the junction of filling and digging.
