复杂岩溶地区桩基区域溶洞处理技术研究

Research on Treatment Technology of Karst Caves in Pile Foundation Areas in Complex Karst Regions

地层条件复杂多样,给桩基工程施工带来许多难题。依托广州白云机场三期扩建工程某安置房项目,全面分析场地溶洞分布情况及对桩基施工影响程度,在此基础上开展复杂岩溶地区桩基溶洞处理技术研究,系统阐述溶土洞与桩基处理技术要点,提出高效的质量保证措施,为其他类似项目提供设计与施工参考。

The complex and diverse geological conditions bring many difficulties to the construction of pile foundation engineering.Based on a resettlement housing project of Guangzhou Baiyun Airport Phase III expansion project,a comprehensive analysis is conducted on the distribution of karst caves on the site and the degree of impact on pile foundation construction.On this basis,research on the treatment technology of pile foundation karst caves in complex karst areas has been carried out,the key points of soil cave and pile foundation treatment technology have been systematically elaborated,and efficient quality assurance measures have been proposed,providing design and construction reference for other similar projects.
