Abstract：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.
