摘　　要：在上海微量沉降和城市设防极高要求的今后一段时期内,海平面上升、基底沉降、欠固结土沉降等不可控因素是地面沉降防治必须要考虑的问题。文章从城市排涝角度研究估算了上海今后最大允许相对沉降量、各不可控因素引发的地面沉降量及有效地面沉降容量。以此为依据,在上海地面沉降三级管控分区的总体框架下,结合城市总体规划,进行了2016-2040年地面沉降防治区划划分,并综合确定各分区地面沉降管控指标,可以为地面沉降防治的精细化管理提供技术依据。Under the circumstances of Shanghai’s trace settlement and the high demand for urban fortification over the nextfew years,uncontrollable factors,such as sea-level rise,tectonic settlement,and unconsolidated soil subsidence,must beconsidered.Based on urban drainage data,this paper presents an estimate of the maximum allowable relative settlement inShanghai,the amount of ground subsidence caused by uncontrollable factors,and the effective land subsidence capacity.The2016-2040control zoning division and management index of each district for ground settlement are determined,in theframework of a three-level management system for land subsidence control in Shanghai.These findings provide a technicalbasis for the fine management of land subsidence prevention.
