摘要：

以圆形截面桩为例，基于修正后的Loganathan公式，利用文克尔弹性地基梁模型、m法计算理论和荷载传递法，建立盾构隧道近接斜交侧穿既有桥梁桩基的变形计算方法. 通过现场监测结果验证计算方法的工程适用性，并利用该方法分析侧穿桥梁桩基施工引起桩身水平挠曲变形的主要影响因素. 结果表明：桩身水平位移和桩顶竖向位移的理论计算结果与监测结果之间的最大误差分别不超过14.6%和2.7%. 与现有方法相比，所提方法的计算结果更接近实测值. 入土段桩身水平挠曲程度与隧道轴心和桩基中心轴线之间的水平距离、隧道侧穿斜交角呈负相关；最大水平挠曲位移与隧道侧穿斜交角呈负相关. 当水平侧穿距离为6.0 m时，最大水平挠曲变形为7.4 mm；当隧道盾构侧穿斜交角为70.0°时，入土段桩身最大水平挠曲位移为15.4 mm.

Abstract:

The calculation approach for the deformation of existing bridge pile foundation caused by diagonal intersection with side penetration construction of the shield tunnel was established. The approach was established based on the modified Loganathan formula, the Winkel elastic foundation beam model, the m-method calculation theory and the load transfer method, taking the circular section pile as an example. The engineering applicability of the calculation approach was verified through field monitoring results, and the method was used to analyze the main influencing factors of horizontal deflection deformation of piles caused by the diagonal intersection with side penetration construction of shield tunnel. Results showed that the maximum error between the theoretical results and the monitoring results for the horizontal displacement of the pile body and the vertical displacement of the pile top were less than 14.6% and 2.7%, respectively. The calculation results of the proposed method were closer to the measured values, compared with that of the existing methods. The horizontal deflection of the pile body in the entry section was negatively correlated with the horizontal distance between the tunnel axis and the center axis of the pile foundation, and the oblique angle of the tunnel side penetration. The maximum horizontal deflection displacement was also negatively related to the tunnel side penetration angle. The maximum horizontal deflection was 7.4 mm at the horizontal side penetration distance of 6.0 m, while the maximum horizontal deflection displacement was 15.4 mm at the tunnel shield side penetration angle of 70.0°.
Key words: shield tunnel    diagonal intersection with side penetration    adjacent bridge pile foundation    deformation law    horizontal deflection deformation of pile
