摘要
从近年日本各地发生的降雨强度来看,降雨强度有增加趋势。基于降雨强度的增加,城市雨水排水措施的选择方法也发生一定变化。通过计算降雨强度的增加趋势,得到5年一遇暴雨强度增加量,假定3个降雨强度增加类别。再通过个案研究的方法,利用降雨强度增加的模拟计算结果,得到在不同研究区域和不同暴雨强度增加的情况下,城市内涝的受灾情况及对该情况下选择相应的排水措施做工程方面的可行性分析。
From rainfall intensity occurring in various parts of Japan in recent years,the rainfall intensity was increased.Based on the rainfall intensity,the formulation and selection methods of urban rainwater drainage measures have also certain changes.The paper obtained the increase of rainfall intensity in five-year flood,assuming 3 scenarios of rainfall intensity,and then using the case study method,according to the simulation results of the increase in rainfall intensity,obtained in different regional and different rainfall intensity increases,for inland inundation characteristics were analyzed and explanation.The selection of corresponding urban rainwater drainage measures were discussed in terms of the feasibility for engineering methods.
