| 摘 要： | 对随机介质理论中参数? 的取值进行研究，提出了适用于不同土层的参数计算公式；隧道周围土体移动采用更加符合实际的椭圆形非等量径向移动模式。在此基础上，对随机介质理论进行修正，提出了适用于地表及土体内部各点位移和变形的计算公式。结合工程实例，通过与实测值、施成华等方法及Loganathan等方法计算结果进行对比分析表明，方法计算得到的结果与实测数据较吻合。

| Abstract: | Based on the research of the parameter ? getting, the calculation formulas of primary parameters applicable to various strata are put forward. The elliptical and non-uniform soil displacement pattern, which is more appropriate for the actual cases, is adopted. With the calculation formulas of ? and the elliptical displacement pattern, the revised stochastic medium theory, applicable to the calculation of surface and subsurface soil displacement is put forward. Finally, comparing the calculated results with the measured field data, the method of Shi and the method of Loganathan, it is proved that the calculated results can be fitted well with the measured field data. |
