摘要

对于浅埋隧道开挖引起的土体位移规律很多学者进行了研究，但对于其水平位移规律的研究却不多。在总结比较现有3种地层沉降公式的基础上，结合其中一种地层沉降理论以及土体不可压缩的假设推导出了浅埋隧道上方土体的水平位移公式，使用该公式对相关文献中的实测数据以及有限元模拟结果进行了拟合对比，证明提出的公式能够较好地预测和描述浅埋隧道开挖引起的土体水平位移规律；另外，基于所推导的地层水平位移公式以及地层沉降理论公式，得出了该方法下的土体位移矢量角公式，并与O’Reilly 和New提出的方法进行了比较，所得结果与相关学者的研究结论一致，证明了该土体位移矢量公式的适用性。此研究成果可为相关实际工程中土体水平位移的计算和控制提供理论参考。

Abstract

Soil movement laws induced by shallow tunnel excavation had been covered by many researchers

but the research on the horizontal displacement induced by tunnel excavation is insufficient. Based on the summary and comparison of three formulas of soil layer’s settlement

a formula for calculating the horizontal displacements in the soil above the tunnel is derived by combining one of the soil settlement theories and the assumption that soil is incompressibility. Results of the formula are compared with the published data in relevant papers and verified by the finite-element simulation results. It is shown that the derived formula is capable enough for forecasting and describing the horizontal displacements of the soil induced by shallow tunnel. In addition

the vector angle’s formula of soil’s displacement is obtained based on the formulas of soil settlement and horizontal displacement; and it’s also compared with O’Reilly and New’s method. The comparison shows the agreement with some researchers’ published relevant conclusions

which verifies the applicability of this formula for soil displacement. The research results will provide theoretical references for calculating and controlling the horizontal displacements of soil in relevant practical projects.
