摘要
针对隧道开挖过程中岩土体的形态结构特征,分析了随机介质理论在隧道开挖中的适用性,在此基础上建立了基于随机介质理论的独岩隧道开挖引起的地表沉降模型,选取了相应的模型参数,并编程实现模型。通过工程实例,分析了各模型参数的影响规律,最后根据K1+700隧道断面实测资料验证了模型的正确性。
In view of the Morphological structure characteristics of rock and soil stratum,the applicability of stochastic medium theory in tunnel excavation was analyzed.Based on this,the stochastic medium model of ground surface subsidence in Duyan tunnel excavation was built,and then the program model brings to effect by selecting the proper parameters.Through the practical example,the paper analyzed the influence rule of each model parameter.At last,the correctness of the model is verified by the measured data with K1＋700 tunnel contour.
