摘　　要：近年来,城市隧道被淹事故时常发生,危害重大,隧道口驼峰是防水淹的关键位置。以城市地下道路、室外排水、防洪防涝等规范及近年水淹事故为基础,结合惠州仲恺高新区某下穿铁路城市隧道设计案例与相关文献,深入研究城市隧道口标驼峰高设计的防洪防涝标准。合理抬高隧道口驼峰标高,有效提高城市隧道的抗洪涝能力和安全性。The paper indicates the hump at tunnel entrances are the key part for flood prevention during the frequent floods at tunnels in recent years,studies the flood prevention and rainwater control standards for the hump elevation design of urban tunnels based on the regulations for underground roads,outdoor drainage,flood prevention and rainwater control and recent flood accidents and combining with the tunnel design case for some underpass railway at Zhongkai High-tech District of Huizhou City and related literature,and clarifies the reasonable elevation of the hump at tunnel entrance can effectively improve the urban tunnels’flood prevention and safety.
