龙羊峡水电站近坝库岸6号滑坡区域的平差计算与稳定浅析

A Brief Analysis of Balanced Error Calculation and Stability of the 6# Slider Area on the Dam-bank in the Longyangxia Reservoir

龙羊峡水电站近坝库岸６、７号滑坡区域位于大坝前面的水库右岸，长约１５．８ｋｍ，高达３００—５００ｍ。自龙羊峡水库蓄水以来，由于黄河上游来水偏枯，水库水位至今未达到设计水位，如果今后水位逐渐上升至设计水位或发生强烈地震等其它特殊情况时，近坝库滑坡体又将发生怎样的变化，有待进一步监测。但目前从精密水准观测点的动态平差结果可以看出：各观测点的数据变化呈现出一定的规律性。从测量误差理论的角度相对来看，６号滑坡体处于稳定状态。

The 6# slider on the dam-bank in the Longyangxia reservoir keeps calm as the present reservoir level is lower than the design level.What will happen if the water leael reaches the design level or in the case of an earthquake?The author analyzes the survey results accumulated in several years;and the variance of the data shows that the slider is till in steady state.
