Urban　water　distribution　network　is　an　important　part　of　lifeline　engineering.　With　the　development　of　the　research　and　construction　of　resilient　cities,　it　becomes　a　practical　need　to　re-examine　the　comprehensive　disaster　prevention　and　mitigation　capability　of　water　distribution　networks　from　the　perspective　of　resilient　cities　and　to　establish　a　quantitative　resilience　assessment　method　that　can　effectively　reflect　the　post-earthquake　recovery　process　of　water　distribution　networks.　A　characterization　of　the　four-stage　recovery　process　of　water　distribution　networks　after　an　earthquake　was　proposed　based　on　the　investigation　of　the　typical　post-earthquake　recovery　process　of　water　distribution　networks.　Then,　a　dynamic　seismic　resilience　assessment　method　for　water　distribution　networks　at　the　emergency　and　relief　stages　was　proposed　based　on　system　dynamics　theory.　This　method　can　not　only　effectively　reflect　the　changing　characteristics　of　water　demand　requirements　from　crowd　and　fire　after　an　earthquake　disaster,　but　also　effectively　assess　the　impact　of　rescue　resources　on　the　functional　recovery　of　the　network,　and　finally　realize　the　dynamic　seismic　resilience　assessment　of　the　water　distribution　network.　©　2023　Tsinghua　University.　All　rights　reserved.
