| 摘 要： | 在对新安江水电站坝基扬压力观测资料进行了分析时发现，一些坝段坝基扬压力偏高，为了保证大坝的安全，采用变化规律分析，统计模型分析和综合成因分析等方法，对坝基扬压力偏高的成因进行了分析，认为影响坝坡3、20、22、23号坝段坝基扬压力的主要因素是上游库水位；其次是基岩温度和降水。结果表明，岸坡坝段强度满足规范要求，坝基面未出现拉应力。建议对排水孔进行全面检查和疏通，并有针对性地采取工程加固措施；对3号坝段加强监测和分析。

| Abstract: | In this paper comprehensive cause analysis of the high uplift pressure in the foundation of Xin'anjiang dam is made by several methods. The affecting factors of the high uplift pressure are revealed. By using three dimensional thin layer finite element method, the analysis on the effect of high uplift pressure on the strength and stability of the dam is carried out. As a result, some conclusions are drawn and suggestions put forward. |
