英文摘要	Typical experimental researches on hydraulic fracturing in the earth-and-rockfill dam with central soil core are reviewed, with corresponding analysis and discussion provided. It is shown that: (1) Experimental methods are necessary in the research on hydraulic fracturing in central soil core. (2) Based on the experimental results, several failure mechanisms and corresponding initiation judgment criteria for hydraulic fracturing have been put forward. However, there has been no effective experimental method to simulate the formation conditions and failure process of hydraulic fracturing. (3) It is feasible to apply centrifuge modeling technique to the research on hydraulic fracturing of earth-and-rockfill dams with central soil core in the initial impounding. (4) A plane-strain centrifuge test can be used to simulate the failure section in hydraulic fracturing to validate the tensile failure mechanism and its synthetic judgment criterion. (5) The major work of experimental research is to simulate the distribution and variation of water pressure inside and outside the central soil core, the stress arching effect, and the stress-induced anisotropy. And much attention should be paid to the stress state in middle and above upstream face of central core in the water level rising. The results present references for similar researches on hydraulic fracturing in central soil core. © 2018, The Editorial Board of Journal of Basic Science and Engineering. All right reserved.
