| 摘 要： | 海绵城市是针对城市建设中解决城市雨洪问题提出的生态理念，其本质是通过渗、蓄、净、排等手段解决城市水资源问题的综合治理.本研究从环境地质条件出发，考虑海绵城市建设中地质体的海绵属性，开展研究区原位双环渗水试验和工程钻孔，针对原始海绵地质条件的降雨入渗最大深度和地表土体渗水速度进行分析，提出海绵渗水、海绵蓄水两个指标.该指标可有效表示及概括海绵城市建设中环境地质适宜性，易得易懂，具有较强的普适性，易于推广.最后以中国中部城市新乡市为例，进行海绵城市建设环境地质适宜性评价.

| Abstract: | Sponge city is an ecological concept proposed to solve the problem of rainfall flood in urban construction, aiming to realize the comprehensive treatment of urban water resources by means of seepage, storage, purification and discharge. Starting with the environmental geological conditions and considering the sponge properties of geological bodies in sponge city construction, the study carries out the in-situ double-ring infiltration test and engineering drilling in the study area, analyzes the maximum rainfall infiltration depth and surface soil water seepage speed in the original sponge geological conditions, and proposes two indexes of water seepage and storage which can effectively represent and summarize the environmental geological suitability in sponge city construction, with strong universality, easy to spread. Finally, Xinxiang City in central China is taken as an example to evaluate the environmental geological suitability of sponge city construction |
