摘要： 大藤峡水利枢纽工程右岸船闸上引航道边坡山体较陡，坡向多为顺向坡，而且多数地层存在软弱夹层，稳定性较差。前缘航道开挖后，影响边坡的稳定和上引航道的安全运行，为此对边坡进行了专门的勘察和试验研究。

Abstract: The slopes right shipgate approach channel at the Big Cane Gorge Hydraulic Project is a relatively steep incline slope. The stability of the rock mass is poor due to the soft layers sandwiched among the hard rock strata. It is anticipated that the rock mass stability will worsen and might result in the operational safety after the excavation of the leading edge of channel. The serious safety concern results in the additional investigation and testing of this slope.
