木桩在处理桩质量事故方面的应用

Timber Pile was Applied to Treat Prefabricated Tube Pile Quality Accident

结合工程实例介绍了木桩在处理预制管桩质量事故方面的应用,某工程施工完毕后的检测表明,预制管桩承载力下降较大,根据场地地质情况进行加固方案的比较,采用预制管桩、木桩组合复合地基来处理桩质量事故。阐述了加固参数的设计过程,并分析加固后基础的沉降情况。竣工后变形观测表明,加固效果良好,采用木桩处理预制管桩质量事故在经济技术上是可行的。

Engineering project in which timber pile was applied to treat prefabricated tube pile quality accident was intro- duced. Test results after construction completion indicated prefabricated tube pile bearing capacity dropped to much degree, reinforcement plans were compared according to location geology situation, and composite foundation with timber pile and prefab- ricated tube pile was adopted to deal with pile quality accident, the reinforcement parameter in design process was elaborated in detail, and foundation settlement after reinforcement was analyzed. What＇s more, deformation observational data after building completion indicated reinforcement effect was good, timber pile is adopted to deal with pile quality accident is feasible in the aspect of economics and technology.
