卵砾石层中地下水库截渗坝设计与施工参数研究

STUDY OF DESIGN AND CONSTRUCTION PARAMETERS FOR UNDERGROUND RESERVOIR INTER-SEEPAGE DAM IN PEBBLE BED

建设地下水库已成为世界上解决供水问题的有效措施和基本手段,其工程关键是建设好地下截渗坝。以烟台滨海平原地带地下水库工程为例,在分析场地水文地质工程地质条件的基础上,详细研究了地下水库截渗坝的设计参数,提出了卵砾石层中地下水库截渗坝新的结构形式,并分析了其结构特点,探讨了卵砾石层截渗坝施工参数和质量控制问题。最后,对其防渗效果进行了检验与分析。

The construction of underground reservoir has become a good measurement and basic method to solve the water supply in the world,and the key of this engineering is the construction of underground inter-seepage dam. The project of the underground reservoir in littoral zone of the Yantai City is taken as a case study. Based on the analysis of ground condition of hydrogeology and engineering geology,the design parameters of the underground reservoir inter-seepage dam in pebble bed are studied. Two new structure types of the underground reservoir inter-seepage dam in pebble bed are proposed. Their structure characteristics are also analyzed. The construction parameters and quality control of the inter-seepage dam in pebble bed are discussed. Finally,the impervious effects are tested and analyzed.
