CONSTRUCTION TECHNOLOGY OF KARST TREATMENT ON PILE FOUNDATION OF HIGH-RISE BUILDING
Hunan is widely distributed with a large number of karst development areas,and the complex geo-logical environment poses severe challenges to the design and construction of high-rise building pile foundations.In response to the difficulty of constructing high-rise building foundations in karst development areas,a pre-treatment method for karst caves using point grouting was proposed based on a high-rise residential project in a city in Hunan Province.The selection process,optimization analysis,and key points of pile foundation construction for high-rise buildings in karst areas were introduced.The practical results have proved that the pre-treatment effect of karst caves is good,and the subsequent pile foundation testing results indicate that the karst pre-treatment and pile foundation construction technology can meet the needs of high-rise building construction.
