Some major engineering geological problems of the Qiyueshan Tunnel exist in engineering construction such as underground river, fracture, broad patulous cranny, high pressure water burst, karst water burst, high stress, coal seam methane and so on.

齐岳山隧道是我国在建的宜昌至万州铁路线的关键性控制工程之一,隧道的主要工程地质问题有暗河、断层、宽张裂隙及伴随的高压涌(突)水、岩溶涌(突)水、高应力及煤层瓦斯等,所以隧道在修建过程中需采用多种辅助工法穿越众多的不良地质段。

A method was proposed for calculating the crack tensor by the elastic wave velocities in the orthotropic rock masses,based on the theoretical relations of crack tensor and compliance tensor and elastic wave velocities,The numerical results show that there is a good correlation with the measured data.

初步尝试了运用弹性波速确定岩体的裂隙张量；首先将岩体视为正交各向异性介质，基于裂隙岩体的应变体积平均，从裂隙引起的间断位移出发，导出裂隙张量与由裂隙引起的柔度张量增量之间的关系；然后根据正交各向异性岩体的波动理论，建立了岩体裂隙张量、等效弹性参数和弹性波速三者之间的相关关系。
