| 摘 要： | 为了准确描述卸荷带岩体的渗透特性,以三峡永久船闸高边坡为例,应用其监测资料,引入应变指标,将岩体卸荷带划分为强卸荷变形带、弱卸荷变形带和卸荷应力应变调整带.观测资料的计算分析表明:与未开挖岩体相比,强卸荷变形带、弱卸荷变形带和卸荷应力应变调整带的渗透系数分别增大了3 138～330,92～27倍和8～1倍.对整个分析过程作了详细介绍.

| Abstract: | How to describe the seepage behaviors of rock mass is a popular concerned problem in engineering circle and academic community.Taking the high side-slope of TGP permanent ship lock as example,by introduction of strain index,the unloading zone can be divided into strong unloading deformation zone,weak unloading deformation zone and stress-strain adjustment zone.The monitoring data showed that compared with the unexcavated rock mass,the seepage coefficients of the three zones increased by 3138~330-fold,92~27-... |
