| 摘 要： | 采用层次性分析原理，研究了金沙江溪洛渡水电站拱肩槽工程边坡各类结构面和临空面组合而成的块体特征，将边坡块体分为确定性块体、半确定性块体和随机块体三个层次；采用块体理论计算评价了不同层次的块体在天然、地震、爆破、地下水状况下的稳定性，并对影响块体稳定性各种内外因素做了敏感性分析，建立了一套非规则边坡块体稳定性分析评价的技术思路和方法体系。研究表明，拱肩槽边坡出现确定性块体的可能性较小，边坡中的不稳定块体大部分为半确定性块体，且规模较小，影响深度有限，切割边界不完善。

| Abstract: | Using the principle of level analysis , the block character, consisting of the different discontinuities and air faces in the spandrel groove slopes of Xiluodu Hydropower Station on Jinsha River , is researched according to the different level. The slopes blocks are classified into three levels: the deterministic blocks, the semi-deterministic blocks and the random blocks. The block stability in all kinds of operating condition, including nature, earthquake, exploding and water, is evaluated by the block theory. The sensitivity of the block stability factors is analyzed. It is revealed that the deterministic blocks in the spandrel groove slopes are little and that most of the non-stable blocks in the slopes are the semi-deterministic blocks, which are in small size, in finite effect depth and in incomplete boundary. |
