摘要
结合位于厚覆砂层岩溶坍陷地区的广清高速公路桥梁钻孔桩的施工,对不同地质情况下的成孔、穿越溶洞处理等关键施工技术进行了阐述和研究,并提出实施技术的保证措施,可为桥梁类似工程施工提供一定的技术借鉴。
Combined with the construction of bored pile in karst-collapsing zone with deep sand layer of Guangqing Highway, key construction technologies of bored pile foundation of bridges are introduced and researched, such as pore boring and cavern crossing, and some assurance measures are put forward, which could be helpful for the similar bridge engineerings.
