摘要
水库蓄水变化是对延寿倾斜观测重要干扰因素之一,通过三维集中载荷模型可推算出库容变化对倾斜观测影响的定量计算、给出理论最小"安静"距离,同时对倾斜观测进行潮汐分析;并研究水库长期、中期、短期各个时期水库库容变化与延寿竖直摆倾斜观测曲线的关系,讨论得出在枯水期水库库容变化对倾斜观测的影响不大,在丰水期理论上水库库容的大幅度变化会对倾斜观测产生影响,但实际并未发现有明显影响。
Changes of reservoir water level is an important interference factor in Yanshou oblique observation.Three-dimensional concentrated load model can calculate the influence of oblique observation capacity,and theoretically give the least ＂quiet＂ distance,and the oblique tidal analysis.Study the relationship between Yanshou vertical pendulum oblique observation curve and the long-term,medium-term and short-term reservoir capacity respectively,conclude that reservoir storage changes in drought period has little effect for oblique observation;in the rainy season,theoretically reservoir storage changes will affect oblique observation,but actually do not have obvious effect.
