宽级配砾石土水力劈裂特性的研究

The property of hydraulic fracture of wide grading gravelly soil

研究表明，当细料含量P<0.1大于25%时，宽级配砾石土可以满足大坝防渗要求；且宜按湿于最优含水量2%～3%填筑。

Results showed that gravelly soil will fulfill impermeability requirement when P_ < 0.1 of fine particle content > 25 % and the effect of impermeability will be more remarkable when filled with 2 % ~ 3 % on the wet side of optimum water content ;
