摘要

茅坪溪沥青混凝土堆石坝是目前世界上最高的沥青混凝土心墙坝之一，由于上坝壳填料与设计料源有所改变，填料特性试验资料较少，有限元计算参数不准，很难客观评估大坝应力变形状态。根据大坝监测资料，采用Duncan-Chang E-? 模型和正算逆解逼近法进行参数反分析，比较客观准确地确定了坝体填料参数，计算结果与观测的实际规律或数值大小非常吻合，为蓄水期评价大坝的应力变形状态提供计算依据。

Abstract

The maopingxi rockfill dam with asphalt concrete core is one of the topmost dam with asphalt concrete core in the world. Because the filling materials as changed

the experimental data is very limited

and the parameters for numerical analysis is not nicety

so it is difficult to evaluate the probable state of stress-strain in the dam body. To obtain the parameters of the filling materials

the monitoring data and optimum theory and finite element method are used for back analysis in this paper. Then

the stress and displacement of the dam are computed and analyzed by using the parameters. The results show that the rule and the value of stress-strain by back analysis accord with the monitoring data very wel1.
