摘要/Abstract

摘要： 郑州市郑东新区龙湖这样大规模的城市人工湖建设在我国尚属首次。在平均湖深4.5 m的前提下以及已有研究成果的基础上，采用现场调研、室内外试验、水质分析及数值分析计算相结合的综合研究方法，结合实际工程经验对龙湖开挖及防渗方案进行研究，结果表明，龙湖主湖区开挖宜采用干法和湿法相结合的“综合开挖”方案；防渗宜采用水中抛土和碾压铺盖相结合的方案，这样既能保证成湖，又不会对周边地区地下水系统和地质环境造成大的影响，还能满足水质要求，从施工设备和工程投资角度来讲也是合理可行的。另外，在龙湖正式开挖之前，应先在现场进行试挖工程，对开挖、防渗设计进行优化。

Abstract: It is the first time in China to construct such a huge lake like the Dragon Lake in the Zhengdong Xin Region of Zhengzhou. On the condition of the average lake depth 4.5 m and on the basis of achievement, we adopt such methods as fieldwork, in-situ and laboratory tests, water quality analysis and numerical analysis to study the excavation of the Dragon Lake and seepage control scheme with experiences of practical project. The result indicates that it is better to use dry and wet methods to excavate the main lake district of the Dragon Lake and to eject soil into water to control seepage. It can form the lake and has no significant impact on groundwater system and geological environment in the nearby area. It also can meet the water quality request. It is also reasonable and feasible from the angles of construction equipment and project investment. In addition, it is considered that it should perform pre-excavation test in-situ and optimize excavation and seepage control programme perior to the formal excavation of the Dragon Lake.

Key words: Dragon Lake, main lake district, excavation, seepage control
