Analysis of Settlement Deformation of Wuluwati Concrete Face Rockfill Dam

摘要

Wuluwati CFRD has been running in a high water level for 8 years by the end of 2008 and complete monitoring data has been gotten since construction.Based on safety monitoring data in recent 10 years,the rheological analysis model of settlement decrement with time was established in this paper according to settlement influence factors (such as water and deadweight)and stress-strain elastic-plastic characteristics of rockfill material.Via the comparison of different final settlement formula with Wuluwati monitoring data,the time curve fitting method was proved to be better. The multivariate statistical model is good at analyzing the settlement influenced by load.Combination of these two methods will help to understand the CFRD material characteristics changing with time comprehensive-ly.
