摘要
采用大型通用有限元计算软件,依据岩土工程中常用的应力应变材料本构模型和渗流计算方法对黏土心墙防渗方案进行了计算,主要分析了大坝在竣工期和稳定渗流期能否安全运行、心墙防渗的作用以及心墙发生水力劈裂的可能性,为检验土石坝黏土心墙防渗设计方案的合理性提供了参考。
Adapting large-scale finite element computation software, according to common stress strain material structure model and seepaging computation method, the paper calculates the earth-rock clay core dam seepage resisting scheme, mainly analyzes the dam safety operation, core wall seepage resisting functions and core wall hydraulic fracturing possibility during the dam completion period and stable seepage period, which has provided some guidance for testing the rationality of earth-rock clay core dam seepage resisting design scheme.
