摘要
讨论了惠东隧道的注浆控制因素对渗流场的影响,分别考虑了注浆层的渗透系数和隧道的排水量与地下水位降深的影响,并通过数值模拟分析给出了它们之间的关系曲线,分析了施工期与运营期的隧道渗流场,指出注浆层渗透系数是控制衬砌背后水压力的主要因素。
The influences of grouting control factors on seepage field of Huidong tunnel are discussed, especially the influences of permeability coefficient of grouting layer and tunnel discharge and dewatering depth of underground water. Relation curve of them is obtained based upon numerical analysis. Author points out that permeability coeffident of grouting layer are major factor influencing the water pressure beneath lining.
