摘　　要：钻孔灌注桩施工技术是道路桥梁施工常见的基础施工技术。钻孔后灌注混凝土或钢筋混凝土形成的基桩能增加地基稳定性及承载能力,但在施工中因场地不平整、土质疏松等,常出现不均匀沉降,诱发钻孔偏斜、坍孔等事故。为此,文章结合某道路桥梁工程对钻孔灌注桩技术的具体运用进行了分析,详细探究了关键工序中的特殊技术措施及处理常见事故技术措施,经超声波检验合格,表示施工技术运用效果理想,可为类似工程提供参考。Bored pile construction technology is a common foundation construction technology in road and bridge construction.The foundation pile formed by pouring concrete or reinforced concrete after drilling can increase the stability and bearing capacity of the foundation.However,due to uneven site and loose soil,uneven settlement often occurs during construction,which induces drilling deviation,hole collapse and other accidents.In this regard,this paper analyzes the specific application of bored pile technology in a road and bridge project,and explores in detail the special technical measures in the key procedures and the technical measures to deal with common accidents.After ultrasonic inspection,the project is qualified,indicating that the application effect of construction technology is ideal,which can provide reference for similar projects.
