摘　　要：广西区域喀斯特地貌的特殊地质,其中溶洞、地下河、暗湖、石钟乳、石笋对于桥梁桩基的影响尤为严重,溶洞良好的处理及桩基的完整性是整个线性工程中桥梁质量把控中关键的一环;桥梁桩基的质量决定了桥梁整体的稳定性及安全性。利用合理的施工工艺及溶洞处理方式方法来提高岩溶桥梁桩基的成桩质量合格率及施工效率,同时达到降本增效的目的。The special geological conditions of karst landforms in Guangxi region,including karst caves,underground rivers,hidden lakes,stalactites,and stalagmites,have a particularly serious impact on bridge pile foundations.Good treatment of karst caves and the integrity of pile foundations are key aspects of bridge quality control in the entire linear engineering.The quality of bridge pile foundation determines the overall stability and safety of the bridge.Using reasonable construction techniques and karst cave treatment methods to improve the qualification rate and construction efficiency of pile foundation in karst bridges,while achieving the goal of cost reduction and efficiency increase.
