First discussed are the problems in which the equations are in ill-condition and the components are difficult to separate but the components in mathematic models are closely related. Then, a synthetic analysis method for the in-situ observed data of dams is proposed. Its key points are as follows. The straight analysis, inverse analysis and 3-D FE methods are synthetically used to separate each component from observed values, and the working behaviour of the dam is judged by using the variation law of time effect...

The straight analysis, inverse analysis and 3-D FE methods are synthetically used to separate each component from observed values, and the working behaviour of the dam is judged by using the variation law of time effect component. Finally, the method is applied to analyse the observed data of a gravity arch dam whose observed values are changing in the initial stage of water impoundment, and the result obtained conforms to the realistic working state of the dam.

In order to study the performance of CFRD, regression analysis and inverse analysis are adopted to investigate the observed data of displacement of the rockfill dam under and after construction. That is an experimental dam in the seventh Five Year Plan of our country. Statistical models and mixing models are established. The findings show that the observed data of displacement of the rockfill dam can be detached according to independent variable factors, that the creepage of the rockfill body during construction can not be neglected and that there are intervals between the experimental values and the values of inverse analysis of parameters of stress strain relation of the rockfill body. If the observed data after water impoundment are analysed and the prognostive equations are established, the monitoring and feedback about safe performance of CFRD can be realized.

The article, in accordance with the characteristics of water impoundment and discharge of the projects on the Yellow River, Suggests an approach to estimate the reduction of the outage time and the increase of water supply on the lower reaches of the Yellow River in the low water period with the Longyangxia and Liujiaxia reservoirs' joint operation. Based on the analysis of the measured data from 1986 to 1992, it is concluded that during the low water season on the lower reaches of the Yellow River, the outage period was annually shortened by 2. 14 months, the water supply was increased by 1. 15 Gm3, therefore, the 2 reservoirs make a great contribution to easing the water shortage on the lower reaches of the Yellow River.

本文结合黄河上、下游蓄、引水特点,首次提出龙羊峡、刘家峡两水库非汛期补水对缩短下游断流时间和增加下游工农业用水的估算方法,并利用1986—1992年非汛期实测资料,估算了相应数值,平均每年缩短了断流时间2.14个月,增加下游工农业用水量11.5亿m3,可增加下游灌溉面积约29.4万ha,为缓解黄河下游水量供需矛盾做出了重要的贡献。
