Abstract: Based on the geological condition and experimental results,this paper analyzed the causes of the sewers drainage subsidence happened often in the quicksand stratum in Shanghai City from three aspects of engineering design and construction. Through comparative analysis of water ob-turation test standards at home and abroad and model checking,this paper put forward for the standards of sewers permitted infiltration volume of water obturation in quicksand stratum area recommended values,in order to reduce the occurrence frequency of pipe drainage subsidence in quick-sand stratum.
