摘要
由于公路工程所处地域的地质比较复杂,特别是软土分布的地区,公路路基稳定及不均匀沉降等问题影响着道路使用的安全性、舒适性,而涵洞作为公路工程中的重要组成部分,运营期间的不均匀沉降会导致明显的跳车现象等,危及行车安全及舒适性。已施工完成的涵洞往往因为净高不足、施工空间狭小,机械设备难以展开限制着涵洞加固方式的选择,而钻孔灌注桩具有施工灵活性强的工艺特点,能在各种有限条件下进行施工,能经济有效地起到加固涵洞的作用。
Due to the complex geology of highway engineering,especially in the distribution of soft soil,the highway subgrade stability and uneven settlement affect the safety and comfort of road use,and culvert as an important part of highway engineering,the uneven settlement during operation will lead to obvious jump phenomenon,endangering the driving safety and comfort.Due to the lack of net height and the lack of construction space,it is difficult to limit the choice of culvert reinforcement method.The bored pile has the technical characteristics of strong construction flexibility,and can be carried out under various limited conditions,and can play the role of culvert reinforcement economically and effectively.
