岩溶及破碎地层对桥梁桩基成孔的影响及处置措施

The Influence and Disposal Measures of Karst and Broken Strata on Bridge Pile Foundation Hole-forming

针对破碎地层及岩溶发育地区桥梁桩基成孔中遇到漏浆塌孔问题,通过钻孔注浆实践,有效地解决了工程中遇到的问题,提高了功效,确保了桩基质量,对以后类似工程的设计与施工有一定的借鉴意义。

For the problems of muddy and leaking of the bridge pile foundation hole-forming in the broken strata and the karst development areas, through drilling grouting practice, this paper effectively solved the problems encountered in the engineering, improved the efficiency and ensured the quality of pile foundation. It also had certain reference for the design and construction of similar engineering.
