城市化对排水工程影响的初步研究 姓 名：陈冬良 班 级：给水排水2006（2）班 指导教师：董志勇 随着城市化进程的加快，城市得到了不断的发展，与此同时，城市也将面临诸多的问题，这些问题间接会对排水工程造成影响。因此，了解并且解决这些问题，有助于我们发展城市排水工程。本文主要研究以下几方面：地面覆盖状况对降雨径流的影响；人口膨胀与污染；地下水超采与地面沉降；城市化对暴雨公式的影响；城市防洪防涝。在研究以上内容的基础之上，最终提出城市化发展对城市排水工程的影响，从而提出一定的解决对策来完善城市排水工程，使城市能够朝着可持续发展的方向发展。 关键词 城市化 人口膨胀 暴雨公式 地面覆盖 地下水 城市防洪 Primary Research of the Influence of Urbanization on the Drainage Works Name: Chen Dongliang Major: Water and Wastewater Engineering 062 Teacher: Dong Zhiyong With the rapidness of urbanization, cities have got incessant development. Meanwhile cities also face up with many problems, which will influence on drainage engineering indirectly. Thus, to comprehend and to solve these problems are very helpful to the development of drainage engineering of cities. This paper tries to have a detailed study on the following aspects: the influence of ground coverage on the rainfall runoff; the population expansion and pollution; the over adoption of groundwater and the sedimentation of surface; the influence of urbanization on the formula of rainstorm intensity; and the flood and waterlogging prevention. Based on the pervious studies, a final discussion of the influence of urbanization on the drainage works of cities will be illustrated in this paper. Thereby some suggestions to perfect the drainage engineering of cities will be put forward to facilitate sustainable development of cities.
