摘要

针对国内水库大坝地震监测系统不完善、不利于现阶段土石坝动力分析理论安全复核,采用GeoStudio软件,结合邓肯E-B模型分析了英菲尔尼罗黏土心墙堆石坝静动力非线性、边坡稳定性及沉降量分布规律,并进行了震害对比验证。结果表明,该方法与实测值吻合,可验证动力分析理论与方法的合理性。
On account of the faultiness of earthquake monitoring system for domestic reservoir dam,which is gone against the safety check of theory for the dynamic analysis of rockfill dam at present,the GeoStudio software is used to analyze the static and dynamic nonlinearity,slope stabilization and the distribution of settlement for El Infiernillo rockfill dam with combination of the Duncan E-B model.And then the seismic damages are comparative analysis.The results indicate that the proposed method is close to the measured value and it can be used to verify the reasonableness of the current theories and methods of dynamic analysis.
