Recently,the non-trivial solutions for 4-dimensional black holes of Einstein-Gauss-Bonnet gravity had been discovered.In this paper,considering a charged particle entering into a 4-dimensional Gauss-Bonnet-Maxwell black hole,we calculate the black hole thermodynamic properties using the Hamilton-Jacobi equation.In the normal phase space,the cosmological constant and Gauss-Bonnet parameter are fixed,the black hole satisfies the first and second laws of thermodynamics,and the weak cosmic censorship conjecture (WCCC) is valid.On the other hand,in the case of extended phase space,the cosmological constant and Gauss-Bonnet parameter are treated as thermody-namic variables.The black hole also satisfies the first law of thermodynamics.However,the increase or decrease in the black hole's entropy depends on some specific conditions.Finally,we observe that the WCCC is violated for the near-extremal black holes in the extended phase space.
