摘要

在深厚覆盖层上建筑的高砾石土心墙堆石坝得到迅猛发展的同时，正确地认识坝体变形规律和合理地数值模拟是不可忽视的问题。堆石坝变形的影响因素多且复杂，监测成果的分析对研究上述问题具有重要意义。以硗碛大坝的监测资料为基础，结合坝体的填筑和蓄水过程，对位于深厚覆盖层上的百米级砾石土心墙堆石坝的变形规律进行了系统分析，并与其坝高、覆盖层深度、河谷宽度等方面都具有相似性的毛尔盖大坝监测资料进行了对比分析。通过分析两座大坝监测结果，对坝体的变形特性进行了规律性总结，对湿化和蠕变作用以及水库填筑和蓄水过程对坝体变形的影响有了一定认识。分析结论可为正确认识以及合理模拟和预测同类坝体的变形特性提供参考和依据。

Abstract

The construction of high gravelly soil corewall rockfill dams on thick overburden layer has developed rapidly in recent years. At the same time getting a clear understanding and a reasonable numerical simulation method of the deformation law is an important problem. The factors that affect the deformation of rockfill dams are many-sided and complex. The measured results of deformation are very significant for the above problems. Based on the monitoring data of Yaoji dam

a 100 m level gravelly soil corewall rockfill dam on thick overburden layer

and combined with the actual construction process and reservoir impounding process

the dam deformation

gravelly soil corewall deformation are analyzed. Maoergai dam has high similarity with Yaoji dam in the height of dam

the depth of overburden

the width of valley. Comparative analysis of these two dams’ monitoring data is also conducted. Based on the analysis

some clear understanding of the deformation law of this kind of dam are obtained. The influence of wetting deformation

creep deformation

construction and impounding method is learned

so as to provide reference for modeling and predicting deformations of similar projects.
