摘　　要：对φ15.43 m泥水气平衡盾构连续2次近距离穿越上海轨道交通3号线高架桩基的施工作较详细的叙述,分析施工难点,提出对施工参数的设定及控制。通过施工监测,盾构2次穿越后立柱的最大沉降量控制在15 mm要求范围内。施工中采取的技术措施可供类似工程借鉴。With the background of Shanghai Metro L3 project, the construction situation of theφ15.43 m slurry air balanced shield machine crossing the adjacent viaduct pile foundation for two times continuously is discussed in detail in this paper. The construction difficulties are analyzed and the set ups and control measures on construction parameters are proposed. Through the construction monitory, the max settlement amount of the pillaris controlled less than 15 mm. Relevant technical measures adopted in this project can provide references for similar projects.
