摘　　要：中国是洪灾多发的国家,洪水灾害造成的经济损失居各类自然灾害之首。同时,洪水灾害造成了大量的房屋倒塌,对人民的生命安全、生产活动多带来了严重的威胁和影响。《建筑结构荷载规范》中除考虑常规荷载外,还考虑了雪荷载和风荷载,但没有考虑洪水荷载对建筑物的作用。综合国内外的研究现状和规范,从洪水荷载对建筑物的作用机理以及建筑物所处地理环境的不同,对洪水荷载的作用方式进行了归类,总结和归纳了洪水荷载的主要形式、大小和洪水荷载组合。同时提出了综合考虑人身安全及建筑物结构安全的住宅建筑洪水破坏模型研究方法。该研究方法为进一步研究住宅结构物在洪水荷载作用下的破坏机理及住宅结构防灾减灾提供参考。Flood disasters occur frequently in China. The economic losses caused by floods are in the first place among all types of natural disasters. Floods collapse a large number of houses, endanger human life and impact on production activities. Load Code for the Design of Building Structures considers normal loads as well as snow loads and wind loads. However, flood loads on the buildings are not included. On the basis of codes and research status at home and abroad, this paper summarized the main types of flood loads, loading condition and loading combinations based on the flood load mechanisms on the buildings and building geographical locations. The paper also proposed a research method of residential building failure model under flood actions on the basis of building and human life safety. The work in the paper provides a reference to further study of the residential structure failure mechanisms under the flood actions and residential building disaster prevention and mitigation.
