在桩基础施工过程中,由于初期地质勘察具有局限性,因此需要对桩底再进行小范围的地质缺陷勘探,并对其进行定位,以为后期建设提供指导。在鸭池河特大桥桩基础施工过程中,采用地质雷达对桩底进行勘探,并对桩底破碎带等缺陷进行定位,以此为依据,采取相应的措施,确保工程质量,达到了较好的效果。
In the process of pile foundation construction, due to the limitations of initial geological survey, it is necessary to carry out small-scale geological defect exploration on the bottom of the pile and locate it in order to provide guidance for later construction. During the construction of the pile foundation of the Yich Chi River Super Large Bridge, the geological radar is used to explore the bottom of the pile, and the defects such as the broken bottom of the pile bottom are located. Based on this, corresponding measures are taken to ensure the quality of the project and reach a better effect.
