Based on the blasting construction of diaphragm wall in Puxi guiding section of East Fuxing Road crossing-river tunnel, the vibration monitoring project on the existing tunnel influenced by explosion construction was put forward, which included measuring points arrangement, test method and vibration test system. Based on monitoring data of explosion vibration, the vibration wave form, velocity, acceleration response, domain frequency and field of measure points were analyzed under the condition of three different location and different detonator. Then according to the safety-judging criterion of explosion vibration, the conclusion that the existing tunnel could be in the base line of safety value under explosion vibration was drawn. Furthermore, the response spectrum characteristics of the existing tunnel subjected to three different explosion vibrations were concluded, these would provide references to the similar projects.
