【摘要】 监测资料表明水口水电站大坝部分坝段坝基横断面扬压力观测孔孔水位出现异常现象,本文通过定性和定量分析,对扬压力异常的物理成因进行了解析,分析表明,出现异常现象是由坝基地质情况所导致,大坝坝基扬压力性态总体正常。更多还原

【Abstract】 Observation data show that the peep hole’s water height of uplift pressure in transverse sections of some monoliths base occur the abnormal phenomena. This paper uses the qualitative and quantitative analysis to analyse the abnormal physical genesis of uplift pressure. The analysis shows that the geologic conditions of dam base lead to the abnormal phenomena, however, as a whole, the uplift pressure of dam base is normal.更多还原
