摘要
总结国内外心墙水力劈裂的数值研究发展,主要成果体现在:(1)数值分析法有总应力分析法和饱和土固结的有效应力分析法两种,而非饱和土固结有效应力分析法是一种新方法;(2)利用数值分析法计算结果判断心墙水力劈裂发生条件时,总应力分析法判别标准更合适;(3)数值分析法的发展,大大促进了心墙水力劈裂发生影响因素的研究。
The achievements in numerical simulation of hydraulic fracturing on core wall of earth-rock fill dam are summarized in detail, which include the recent development in China and abroad. Main achievements are listed as follows. （1） Numerical analytical methods include the total stress method and the effective stress method based on the consolidation theory of saturated soil, which are routine methods for numerical analysis of hydraulic fracturing on the core wall of rockfill dam, while the effective stress method based on the consolidation theory of unsaturated soil is a new one. （2） It is more reasonable to use the total stress method to judge the hydraulic fracturing on the core wall than the effective stress method. （3） The numerical analytical methods promote the study of the influential factors of hydraulic fracturing on the core wall.
