免共振钢管桩施工对桩周环境的影响

Influence of Non-resonance Steel Pipe Pile Construction on Environment around Piles

摘要:

与传统沉桩工艺相比,高频免共振法施工具有施工效率高、噪音污染小、泥浆污染少、对周围环境影响小、适用地质范围广等特点,但在紧邻地铁施工时对地铁影响的研究较少,本文依托杨高中路改建工程,通过对临近地铁的桩位附近进行原位监测试验,分析了高频免共振沉桩施工对桩周环境的影响,保障地铁运营安全。

Abstract:

Compared with the traditional pile-sinking technology, the high frequency non-resonance construction method has the advantages of high construction efficiency, less noise pollution, less mud pollution, less influence on the surrounding environment and wide range of geological application. But there is less study of construction influence on the adjacent subway. Relying on Middle Yanggao Road Reconstruction Project, the in-situ monitoring test is carried out near the pile position close to the subway. The influence of high frequency non-resonance pile-sinking construction on the environment around the piles is analyzed to ensure the safety of subway operation.
