安康坝址右岸非溢流坝段下游缆机平台的开挖边坡,在1981年开挖过程中产生了岩体局部倾倒现象,总方量约5,000米~3(见图1)。开始,倾倒体的方量较少,但随着上部倾倒松散体的清除,倾倒范围进一步扩大,前后处理了半年多时间。这一现象可供同类地区借鉴,特作如下介绍。 Excavation of the cable platform downstream of the non-overflow dam section on the right bank of Ankang dam site resulted in a partial dumping of rock mass during excavation in 1981 with a total square volume of about 5,000-3 (Figure 1). Initially, the amount of pouring body less, but with the upper part of the dumping loose bulk, dumping range to further expand, before and after handling more than six months time. This phenomenon can be used for reference to similar regions, especially for the following introduction.
