摘　　要：近年来,西北地区由于常年的季节性暴雨,使得已建城市、园区内涝现象多发,解决该问题主要在城市、园区建设的前期阶段;在园区排洪系统建设中,不光计算洪水流量,还应计算泥石流流量;不光要求排洪渠布线顺畅,还应遵循园区总体规划,兼顾现有建筑影响;不光计算排洪渠过水断面计算,还应通过排洪渠不淤计算。In recent years,due to perennial seasonal rainstorm,the waterlogging in the built cities and parks has occurred frequently in the northwest China.The solution to this problem is mainly in the early stage of the construction of cities and parks.In the construction of flood drainage system in the park,not only the flood flow,but also the debris flow should be calculated.It is not only required that the drainage channel be laid smoothly,but also should follow the overall planning of the park,taking into account the impact of the existing buildings.Not only the crossing section of the flood drainage channel is calculated,but also the non-silting of the flood drainage channel is calculated.

关 键 词：洪水流量 泥石流流量 布线 不淤计算
