复杂岩溶区高速公路桥梁桩基勘察设计与施工技术

Investigation and design and construction technology of pile foundation of expressway bridge in complex karst area

文章以大庆至广州高速公路南康至龙南段扩容工程岩溶区桥梁为工程背景,针对中小型、中大型和复杂三类不同发育程度岩溶桩基,从勘察、设计和施工多方面进行总结和分析,供同类工程情况参考。

This study takes the expansion project of the bridge in the karst area of the Nankang Longnan section of the Daqing Guangzhou Expressway as the engineering background,and summarizes and analyzes the survey,design,and construction of three types of karst pile foundations with different development levels:small,medium,and complex,providing reference for similar engineering situations.
