摘　　要：根据保障应急应战部队机动中克服江河湖沼障碍的需求,通过对南方水网稻田地区交通与地形特点的分析,结合321型装配式公路钢桥器材的特点,提出了长大应急通道架设时根据水域情况可以采用急造军路、钢桥、钢桥与浮桥段相结合等总体方案;针对321型装配式公路钢桥器材作为架设通道主体,提出了30 m一跨的3种技术方案,在对3种方案进行分析比选后,确定采用上承式通道方案;详细介绍了上承式方案的结构组成,并分析了该方案的特点,论证了水网稻田地域架设长大应急通道的可行性。To meet the requirements of emergency response troops in overcoming the obstacles such as rivers, lakes and muddy districts during maneuvering, upon the basis of analyzing the traffic and terrain characteristics in water paddy fields of South China regions, and taking into account the characteristics of Type-321 assembled highway steel bridges, put forward in the present paper are the overall schemes for erecting long and large emergency passages over various waters according to the specific circumstance of different waters, including building emergency military roads, erecting steel bridges, steel bridges in combination with pontoon bridge sections. Aiming at using the highway steel bridge equipment as the main body of the passage, three technical schemes with the span of 30 meters are presented in the paper. Upon the basis of the comparative choice of the three schemes, the deck-type scheme is finally chosen. Introduced in detail in the present paper is the structural composition of the deck-type scheme, with its characteristics analyzed and the feasibility of erecting long and large emergency passages in water paddy fields verified.
