按照前文分析,上海市区防汛墙受地面沉降和结构自身等因素发生沉降,致使防汛能力已有不同程度下降,预测未来,虽然现有防汛墙自身结构沉降已逐步趋向稳定,但受近墙工程及其他人为活动引起结构沉降是不确定的,尤其是起主导影响的上海地区地面不均匀沉降仍将继续,势必不断加重对防汛墙防洪能力的影响,若不及时采取有效措施,将难 According to the analysis above, the flood control wall in Shanghai is affected by the subsidence of the ground and the structure itself, resulting in the decrease of flood control ability in varying degrees. In the future, although the settlement of the existing flood wall itself has been gradually stabilized, And other activities caused by sedimentation structure is uncertain, especially in the dominant impact of uneven ground settlement in Shanghai will continue, is bound to continue to increase the flood control wall flood control capacity, if not timely and effective measures will be difficult
