高桩码头灌注桩岩溶处理技术

结合肇庆新港高桩码头工程实例，针对工程地质条件及溶洞的不同类型，从技术、经济等方面进行比较分析，采用静压化学灌浆法、套内护筒法等施工技术处理溶洞，处理方法有效可靠，各项技术指标均满足设计要求，不仅缩短施工工期，而且达到工程质量与经济效益的双赢效果。

Karst processing technology for cast-in-place pile of high-pile wharf

Combined with Zhaoqing new port high-pile wharf engineering example, according to engineering geological conditions and different types of caves, this paper carries on the comparative analysis from the technical , economic, and other aspects, uses the static chemical grouting method and the construction technology kit casings classification method to deal with the cave. The methods are effective and reliable, and the technical indicators can meet the design requirements. It can effectively shorten the construction period to achieve win-win results of the construction quality and economic benefit of the project.
