摘要:

总结了下穿隧道开挖对邻近桩基产生的影响和小孔扩张-收缩理论的相关研究,分析了两阶段分析法、整体分析法和室内模型试验3种常见研究隧道-桩基相互作用方法的优缺点,同时在总结岩土介质小孔扩张-收缩理论研究及其在桩基工程和隧道工程中应用的基础上,指出了现有小孔扩张-收缩理论在研究浅埋隧道开挖中的不足。提出一种关于浅埋隧道-桩基相互作用的求解思路,即考虑地表效应的影响,采用有限介质小孔扩张-收缩理论进行求解。给出了该方法的初始计算模型和计算流程图,并将理论计算所得各阶段土体的位移场与离心模型试验结果进行对比,验证了方法的可行性,最后基于此计算模型给出了各阶段土体的应力场及变化量。结果表明:小孔扩张-收缩理论可以考虑三维隧道开挖对邻近桩基的影响,为解决隧道-桩基相互作用提供了新的解决思路。

Abstract:

The influence of tunnel excavation on the adjacent pile foundations was reviewed, and the relevant studies on the theory of cavity expansion-contraction were summarized. The advantages and disadvantages of existing three common research methods for tunnel-pile interaction were analyzed, including the two-stage method, overall analysis method and indoor model test. On the basis of summarizing research on the theory of cavity expansion-contraction theory in geomaterials and its application in pile foundation engineering and tunnel engineering, the shortcomings of the existing cavity expansion-contraction theory for the study of shallow tunnel excavation were pointed out. Therefore, it was proposed that the interaction between shallow buried tunnel and pile foundation should be solved by using the theory of cavity expansion-contraction in a finite media considering the influence of surface effect. In addition, the initial calculation model and calculation flowchart of the method were provided, the displacement field of each stage of soil obtained by theoretical calculation was compared with the results of centrifugal model test, and the feasibility of the method was verified. Finally, based on the model, the stress field and variation of soil in each stage were given. The results show that the influence of three-dimensional tunnel excavation on adjacent pile foundations can be considered in the theory of cavity expansion-contraction, which provides a new solution to the interaction between tunnel and pile foundation.
