| 摘 要： | 三峡船闸高边坡岩体稳定性主要影响因素为结构面发育情况。施工期地质超前预报，着重从结构面网络角度进行处理，其方法为：编录统计整理结构面，建立高边坡的三维立体网络图形；岩体质量分析，进行概率模型与确定性模型的耦合模拟；块体判断分析，对临空面块体、内部块体进行判断、搜索、分析；稳定性计算分析。

| Abstract: | The stability of high slope rock of Three Gorges shiplocks is mainly controlled by discontinuity in rock, so stability or unstability forecast of shiplock slopes should be done from processing and analyzing network during construction The methods include generating three dimension network graphics of whole shiplock slopes by using discontinuity network software,analyzing rock quality by modelling with coupling probability and determinate models,searching and analyzing surface block and inner block ,and calculating block stability coefficient |
