摘　　要：长江漫滩相软土分布范围广、工程性质差、危害大,该地区既有建(构)筑物地基薄弱,往往因沉降过大或不均匀而产生开裂甚至破坏,给社会造成了一定的安全隐患和经济损失。为了查明长江漫滩相软土地区既有建(构)筑物病害产生的原因和特点,通过现场调查、资料收集等方法进行了研究。结果表明,地质因素、建(构)筑物本体因素、周边地下工程活动诱发因素是建(构)筑物产生病害的主要影响因素。最后,根据不同病害类型,提出相应的治理措施,并从工程规划、设计、施工、运营角度提出风险防控建议,可为类似地区建(构)筑物病害治理和预防提供参考。The Yangtze River floodplain soft soil is widely distributed,with poor engineering properties and great potential harm to the buildings and structures above it.The foundation of existing buildings and structures in this area are usually vul-nerable,and often cracks or even are destroys due to the excessive total or differential settlement,which has caused certain safety hazards and economic losses to the society.To identify the causes and characteristics of the defects of existing buildings and structures in the soft floodplain area of the Yangtze River,the field investigation and data collection were performed.The results show that geological factors,building and structure factors and inducing factors of the surrounding underground engi-neering activities are the main influencing factors of these buildings and structures defects.Finally,according to the different types of defects,the corresponding control measures are proposed,and the risk prevention and control suggestions are recom-mended from the perspective of engineering planning,design,construction and operation,so as to provide reference for the treatment and prevention of building diseases in similar areas.
