1 引言近年来,我省一些城市为了充分利用有限的水资源,增加城市空气湿度及城市水面景观,改善城镇居民的生存生活条件,保障城市供水,提高城市品位,在市区河道上开始兴建橡胶坝。如南阳市在白河上已修建三级水面、洛阳市在洛河上修建三级水面,另外郑州市、漯河市等多座城市均建有市区水面工程。这些水面工程,库区地质大多为砂土或砂卵石,为减少渗漏,节约水源,库区渗漏量计算及防渗措施就显得尤为重要。本
1 Introduction In recent years, some cities in our province in order to make full use of limited water resources, increase urban air humidity and urban surface landscapes, improve the living conditions of urban residents, to protect urban water supply, improve urban quality, in the urban river began to build rubber dam. For example, Nanyang City has constructed three water levels on the Baihe River. Luoyang City has built three water levels on the Luohe River. In addition, a number of cities such as Zhengzhou City and Luohe City have built urban water surface projects. These surface engineering, most of the reservoir area of sand or gravel, in order to reduce leakage, water conservation, reservoir leakage calculation and seepage control measures is particularly important. this
