摘要
针对柴河特大桥岩溶强发育区桩基施工特点,以12#主墩桥梁桩基施工为例,对岩溶强发育区桩基施工方法及特点进行阐述,重点对地质核查、施工准备、外钢护筒设置和冲击钻孔施工等流程进行系统说明。研究成果为岩溶地区桥梁桩基施工提供了参考。
For Cai He the carge oridge of the large bridge pile foundation construction characteristics, for 12 # main piers of the bridge pile foundation construction as an example, the strong karst development area, elaborates the methods and characteristics of pile foundation construction, focusing on geological verification, construction preparation, the outer steel liners set and impact drilling construction process, such as the system description. This research provides reference for bridge pile foundation construction in karst region.
