摘要
扬压力性态是反映大坝安全与否的重要指标,通过定性和定量分析方法,从大坝劈头裂缝稳定性、地质情况、坝基运行性态、坝基渗流监测资料分析等多方面,对桓仁水电站坝基扬压力强度系数超限原因进行分析。建立回归统计模型,研究气温、水位以及时效对扬压力强度系数的影响,诊断可能存在的异常现象,分析查明超限原因,并提出防范建议,对确保大坝安全稳定运行具有重要意义。
The uplift pressure behavior is an important indicator reflecting the safety of a dam.Through qualitative and quantitative analysis methods,the reasons for the exceeding of the uplift pressure strength coefficient of the dam foundation of Huanren hydropower station are analyzed from various aspects such as stability of dam splitting cracks,geological conditions,dam foundation operation behavior,and dam foundation seepage monitoring data analysis.Establishing a regression statistical model to study the effects of temperature,water level,and time on the strength coefficient of uplift pressure,diagnosing possible abnormal phenomena,analyzing and identifying the reasons for exceeding the limit,and proposing preventive suggestions are of great significance for ensuring the safe and stable operation of the dam.
