In this paper,two numerical schemes for solving BBM type viscous fractional equation are constructed. We analyze the stability and error estimates of the two schemes,a rigorous analysis shows that the proposed schemes are unconditionally stable,and the convergence of two schemes are convergent with order O(Δt3/2+N1-m),numerical results are consistent with the known theoretical prediction.
