摘要
通过对８种因素、７７种状态的信息量计算，得出研究区稳定性信息的权值。在取得１２８个预测单元的信息量预测值之后，划分出５３个活动单元和较活动单元，其中１２个为新预测的不稳定区。与仪器观测结果比较，一些新预测区的不稳定性得到证实。研究表明，信息量法对评价工程高边坡稳定性。
This paper deals with the information value mehtod for stability study of large scale and high rock slopes of engineering for the first time. On the basis of engineering geological work of some hydroelectric station slopes, the information value of 8 factors and 77 conditions were computed. The information prediction values of 128 prognostic units were acquired. Finally, it was discovered that 53 units are unstability units in which 12 units belong to new prognostic unstability units. By instrumental observation, some new prognostic unstability units were confirmed. It shows that the information value method has important significance for removing the hidden danger of engineering.
