摘要
生态环境的变化以及城镇化速度过快,导致近年暴雨频发、城市内涝、农田积水、水坝水位升高等情况的发生并伴随大量的灾难,同时水资源的缺乏也存在于大部分地区,因此将水储存起来进而再次利用是非常重要的。砂岩具有良好储集效果。根据西安地区的一些地下水地质报告,通过出水速度可以确定排水速度符合降水时的要求,通过地质和砂岩渗透率计算分析确定地质储水量。结果表明:砂岩储层的储水效果是适合城市排水系统解决内涝灾害问题要求的,它的储水量公式对于透水材料也具有普适性,根据各地不同的砂层情况设计不同的储水方法,既能减少洪涝灾害又可实现水资源可持续发展,为海绵城市建设提供了一个重要的方案。
Due to changes in the ecological environment and the rapid urbanization,heavy rains have occurred frequently in recent years,so urban stagnation,water accumulation in farmland,rising water level of dams,etc.,accompanied by a large number of disasters,and the lack of water resources also exists in most region,so it is very important to store and reuse the water.The sandstone has a good reservoir effect.For some groundwater geological reports in Xi’an,the discharge velocity can be determined to match the precipitation.According to the requirements of geological and sandstone permeability data,the geological water storage capacity is determined.The results show that the sandstone water storage system can effectively accommodate urban water storage and reduce urban stagnation.The sandstone water storage formula is also universal for permeable materials.The design of different sand storage conditions can not only reduce flood disasters,but also achieve sustainable development of water resources,providing an important solution for the construction of sponge cities.
