Abstract: Through developing field micro-seismic trial , the characteristics of vibration attenuation of bridge pile construction and sphere of inf1uence were analyzed to assess their impact on the buried pipeline nearby. It is concluded that the amplitude of vibration energy have been enlarged with the presence of the pipeline; it should make the smface peak velocity above the pipeline as the main control index in routine vibration monitoring of pile foundation construction adjacent to buried pipeline. By analyzing positioning of impacting vibration source , the rupture area of rock and soil around the pipeline caused by the vibration was determined , and the conesponding security ll1easures for pipeline protection was proposed. It provides a new trial ll1ethod of control technology for pile foundation construction.

摘要: 通过开展现场微地震试验,对桥梁桩基施工振动波的传播衰减特性和其影响范围进行了相关分析,对振动对邻近埋地管道所造成的影响进行评估。通过研究显示:管道的存在使得振动能量幅值有所放大;当在埋管附近进行常规桩基施工作业,其施工振动监测的主要控制指标为管道上方的地表峰值振动速度;通过冲击振源的定位分析,确定了由振动引起的管道周围岩土体的破裂区域,进而为埋地管道的安全保护提出了相应措施,同时也为桩基施工振动的控制研究提供了一种新的试验方法。
