Abstract: Based on the safety monitoring results of reconstructed Fengman dam, the deformation development law and distribution characteristics of Fengman gravity dam during the first impoundment are studied and analyzed. The results show that the horizontal deformation, settlement and inclination of the dam are all within a reasonable range. The distribution and development trend of deformation go well with general law. The deformation of transverse joint is small, and there is no anomalous development trend. The dam deformation is generally within the normal range.

Key words: reconstruction of Fengman dam, first impoundment, monitoring analysis, dam deformation

摘要: 以丰满大坝重建工程安全监测结果为基础,研究分析了丰满重力坝在首次蓄水期间的主要变形发展规律和分布特征。结果表明:大坝的水平变形、沉降变形和倾斜角度均在合理范围内,变形分布及变化趋势符合一般规律,大坝横缝变形较小,且无异常发展趋势,坝体变形总体处于正常范围。
