Simulated　electric　field　distribution　in　concrete　by　using　of　ANSYS　finite　element　analysis　software,　researched　influences　of　some　factors　on　electric　field　strength　and　electric　potential　in　concrete.　Which　include　resistivity　of　cement　soil　and　its　electric　field　strength　are　inversely　proportional　and　the　electric　potential　distribution　is　less　affected　by　resistivity　changes,　applied　voltage　is　proportional　to　electric　field　strength　and　potential,　the　more　the　number　of　cathode　induces　the　greater　and　uniform　of　the　strength,　electric　field　distribution　within　cement　soil　becomes　sparse　and　its　values　are　relatively　smaller　with　the　anode　spacing　increasing,　electric　field　strength　of　cement-soil　is　more　intensive　and　its　distribution　is　more　uniform　and　also　its　values　is　relatively　larger　with　the　decreasing　of　cathode　spacing.
