The　water　seepage　of　underground　structure　is　the　serious　problem　in　the　construction　engineering,　and　becomes　one　of　the　most　harm　in　current　infrastructure　with　the　huge　potential　safety　hazard　and　economic　loss.　The　electro-osmosis　technology　is　once　widely　used　in　the　fields　of　soft　ground　stabilization　of　rock　engineering,　the　biological　pharmacy　and　the　oil　production　engineering　in　China.　This　paper　referred　experiences　of　overseas,　combined　electric　pulse　signal　and　the　electro-osmosis　technology　to　reduce　seepage　of　the　underground　structure,　and　solved　underground　structure　water　seepage　problems.　The　paper　comprehensively　analyzed　the　research　status　of　the　technology　at　home　and　abroad　and　its　feasibility　in　theory,　also　introduced　the　general　implementation　methods　of　projects,　and　carried　on　the　comparison　of　the　pulse　electro-osmosis　technology　and　the　traditional　moisture-proof　technology　in　application.
