摘　　要：通过水文水力计算对黄延高速公路全段涵洞的泄洪能力进行复核，结果表明有两处涵洞不满足一百年一遇洪水的无压泄洪要求，需要进行结构改造或按有压泄流进行复核，确保黄延高速通车后的行洪安全。The discharge capacity of culvert along the Huangyan highway is analyzed by hydrological and hydraulic calculation. The results show that there are two culverts whose discharge capacity is not enough high on the condition of no pressure for the floods whose recurrence interval is 100 year. So their structure had to be modified or the checking are carried out again on the condition of pressure to make sure that hignway is safe during flood oeriod.
