由于岩溶地质通常溶沟、溶槽、石芽、溶洞、土洞、暗河等发育，岩面起伏较大，冲孔灌注桩是比较适应的一种桩型，广被应用。但冲孔灌注桩施工过程仍然存在很多问题，如漏浆、串孔、塌孔、偏斜孔、卡锤、断桩等。这些一直以来都是困扰岩溶地质桩基质量、安全、进度的重要因素。本文结合工程实例，阐述岩溶地质冲孔灌注桩施工方法和技术措施，以确保其施工进度和施工质量。

Due to karst ground usually have stone groove, stone bud, cave, soil cave, underground river and uneven rock surface, bored pile is more suitable pile type and is widely used in the region.However, the construction process of bored pile still exists many problems, such as leakage, string hole, hole collapse, partial holes, hammer stuck, broken pile and so on.These problems have always been an im-portant factor affecting the quality, safety and construction progress of the pile foundation in the region.Combining with the engineering ex-ample, this paper described bored pile construction methods and technical measures in the Karst ground in order to ensure the construction progress and quality.
