CHARACTERISTICS OF EVOLUTION OF POTENTIAL EVAPORATION IN TIANJIN REGION OF CHINA

The characteristics of seasonal and annual changes of potential evaporation, the variations of thermal and dynamical evaporation in different seasons and the relationships between potential evaporation and meteorological elements were analyzed according to the observed data of 9 stations from 1961 to 2001 in the Tianjin region of China. Analyses indicate that thermal evaporation is the main part of the potential evaporation and offers about 90%o fraction of to it in summer, while in winter the dynamical evaporation is greater than the thermal one, especially in Jan. , offering 100% contribution, that the influence of temperature on the change of potential evaporation was much larger than that of wind, vapor pressure and sunshine duration, and potential evaporation increased by 30. 33mm with temperature raise 1℃, and that potential evaporation had a surprising increasing tendency, in particular during the recent decade, with the velocity of 4. 22mm/a. The potential evaporation in the Tianjin region will be higher than the past, especially on the global warming background, so that it has the great effects not only on the climatic forcing changes, but also on development of city and economy.     

刘家峡水电站大坝坝基承压水异常分析

2003年某水电站坝基承压水水压发生十分罕见的大范围、大幅度异常突降，一夜之间承压水水位下降23.8 m，自动化监测系统记录了突变全过程。文中根据自动化观测数据，分析异常期间大坝变形、扬压力、渗流量的变化以及对大坝安全的影响;并根据形变场与渗流场相互作用，提出坝基承压水水压与基岩岩块变形位移相互作用的机理关系，得到了实测数据的支持和验证。坝基承压水异常后，承压水水位与库水位的相关关系甚好，其相关系数大于0.997，标准差小于0.07 m，回归方程满足真值方程的条件，对形变场与渗流场耦合作用和短时间形变回弹
