摘要
在隧道突水预测中，由于含水围岩渗透具有较强的非均质各向异性，常影响隧道实水预测、预报的准确性。为了解决这个问题，本文以中国南昆铁路二排坡隧道为例，提出了用渗透张量新方法进行隧道含水围岩非均质各向异性渗透的计算分析，以提高隧道突水来源、突水位置、以及突水量的预测预报准确度。
n the prediction of gush water inistunnel, iiis quite difficult to predict the gushwater accurately due to the surrounding rock with obvious inhomogeneity and anisotropy.This paper, taking the Erpaipo Tunnel in the Nan-Kun Railway as an example, presents anew permeability tensor method to make an analysis and calculation of inhomogeneous andanisotropic permeability on the aquiferous tunnel-surrounding rock, It improves the accuracy of prediction of the gush water source, site and quantity.
