摘　　要：收集北京市四环路内全部采用强制排水下凹式立交桥的设计资料,从下凹式立交占比、下凹式立交相关道路的路网功能、立交选型及平面布置、纵断面、横断面等方面,对设计资料进行整理和统计,定性分析设计指标对雨水管理的影响,提出基于雨水管理的下凹式立交设计需额外考虑的影响因素及应对措施。The article introduces the design data of the sunken interchanges all with the forced drainage within Ring Road IV of Beijing from the proportion of sunken interchange, the relative road network functions of sunken interchange, and the selection, plane layout, longitudinal section and cross section of interchange, qualitatively analyzes the influence of design index on the rainwater management, and puts forward the influence factors and the countermeasures additionally considered for the design of sunken interchange based on rainwater management.

关 键 词：下凹式立交 立交设计 雨水管理 立交特点
