摘　　要：结合自贡市东部新城的防洪标准、水文特点,采用暴雨强度公式法、暴雨推理法、地区经验公式法和径流形成法等四种方法计算涵洞防洪流量,验算涵洞孔径,提出小流域涵洞水文计算的合理方法,更好地提升了涵洞的经济性、实用性和安全可靠性。Combining with the flood control standard and hydrological characteristics of the new town in the east of Zigong city,this paper uses four methods,including rainstorm intensity formula method,rainstorm inference method,regional experience formula method and runoff formation method,to calculate the culvert diameter,and puts forward a reasonable method for calculating the culvert hydrology in the small watershed,which improves the economy,practicability and safety reliability of the culvert better,with a view to reference to the dimension calculation in the culvert design of the relevant person.
