黄土地层浅埋暗挖地铁隧道施工引起地表沉降预测

摘要:

在我国城市地铁隧道施工引起的地表沉降的研究中，随机介质理论应用相对较晚。在对不规则隧道断面施工引起的地表沉降预测的过程中，进行了大量的简化，并且预测结果与工程实际出入较大。本文在修正的随机介质理论基础上，利用标准变换原理，得出了随机介质理论解析公式的极坐标表达式，使其对于任意断面隧道施工引起的地表沉降计算同样适用。在上述讨论的基础上，通过对实际工程的验证，证明了上述方法的有效性和可靠性。

Abstract:

Stochastic medium theory is applied in the research of the ground settlements Induced by subway tunneling lately. There are a lot of simplification and many difference between the predict results and the engineering practice in the prediction process in irregular tunneling. This paper gives expression of the ground settlements Induced by any section tunneling using standard transform principle on the base of the correctional stochastic medium theory. On the basis of above discussion, proving this method is effective and reliable by the verification.
