摘　　要：通过现场检测及监测结果,分析坝基柱状节理岩体开挖后的松弛持续时间、松弛深度及变形特性,通过在复杂工程中检测与监测结果互为验证,提高对柱状节理玄武岩变形特性的认识,为坝基开挖支护设计提供参考。Based on the field detection and monitoring results,the relaxation duration,relaxation depth and deformation characteristics of columnar basalt at dam foundation after excavation are analyzed.It is seen that detection and monitoring results can verify each other in complex projects.In this way,deformation characteristics of columnar basalt are better understood,which provides reference for the excavation and support design of dam foundation.
