| 摘 要： | 在利用随机介质理论预测城市隧道施工引起的地表沉降时,对于地层主要影响角的取值存在较大的争议.地层主要影响角与地层条件有关,其取值大小直接影响着地表沉降槽的形态,在总结前人算法的基础上,提出了一种主要应用于硬粘性土层中的地层主要影响角计算公式,该公式能较好地反映粘土地层隧道施工引起的地面沉降特性,具有一定的工程参考意义.

| Abstract: | There are some disputes on adopting the value of the main influence angle of stratum when using predicting the ground settlement caused by tunnel construction in city with the stochastic medium theory.The main influence angle of stratum is related to the condition of the stratum concerned and then the profile of the surface settlement trough is directly impacted by the magnitude of its value.Based on the existed arithmetics,an expression that mainly applied to calculating the main influence angle of the str... |
