摘　　要：为了提高桥梁的安全性,节约资源,以桥梁工程等理论为指导基础,对某旧桥桩基采用放射波法进行完整性检测。在分析放射波图形的基础上进行桩顶承载力的分析,得出桩基础工程完整性和承载力的安全状况,探索了一种新的桥基检测思路,对确保旧桩桩基安全性和节约建设资金具有重要意义。In order to improve tile safety of the bridge and save resource, taking bridge engineering as theory basis, radiation wave method is used to carry on the integrity testing of old bridge pile foundation. On the basis of the analysis of radiation wave pattern, the bearing capacity of pile is analyzed, the integrity of pile foundation en gineering and the security situation of bearing capacity are obtained, and a new idea about bridge foundation test ing is put forward. It has important significance to ensure the safety of old pile foundation and conservation of re sources.
