摘要/Abstract

摘要： 基于平面应变原理，考虑岩土体的不可压缩性，采用国内外适用性较强的Peck公式验证所提出的考虑隧洞直径与上覆土层厚度、土体削减、盾尾间隙、围岩土质概况等因子对影响角参数、任意深度沉降槽宽度对数值的影响及取值区间。拟采用具体参数用于随机介质理论中，探讨了参数变化对Park位移模式3引起的隧道轴线上任一深度土层的三维空间位移的影响。通过相关具体算例结果表明：采用考虑围岩土体性质参数比较合理，且在工程上应用偏于安全。

Abstract: First of all, based on the principle of the plane strain, considering the incompressibility of the rock and soil mass, the Peck formula which was quite applicable at home and abroad was applied. The influence of the factors considering the tunnel diameter, the buried depth, the soil cutting, the caudal space and the surrounding rock properties of soil factors on the influence angle parameter, the arbitrary width coefficients of seelement trough on the value and value range was verified by the Peck formula. Aand then, the proposed specific parameters were used in the stochastic medium theory. Finally,the influence of the parameter change on the three-dimensional displacement of the soil at arbitrary depth in tunnel axis caused by the third mode of the Park displacement mode was discussed. Through the relative case studies, the results show that:the parameters considering the nature of the surrounding soil are more rational and inclined to be safe in engineering application.

Key words: geotechnical engineering, the surrounding soil, peck formula;major influence angle, width coefficients of settlement trough, gap parameter
