三峡工程永久船闸高边坡稳定性研究中的几个主要问题

SOME MAIN PROBLEMS ON THE STABILITY OF HIGH PERMANENT SHIPLOCK SLOPE FOR THREE-GORGES PROJECT

摘要: 永久船闸高边坡稳定性问题一直为各方所关注 ,本文利用大量监测资料和测试成果对边坡变形现状 ,开挖结束后的变形趋势 ,岩体卸荷带特征及时效变形等几个方面进行了详细分析 ,并对施工期后边坡岩体的变形与稳定过程 ,以及卸荷带对边坡稳定性的影响等做了预测和评价。

Abstract: The problem of high slop stability for permanent shiplock attracts many attention in the world.In this paper the state of slope deformation, deformation tendency after the exploration, characteristics and time effect of the deformation by unloaded zone of rock mass are analysed by using monitoring data and test results.Then deformation stages and amplitudes and the effect of unloaded zone on the slope stability are predicted and assessed.
