结合蒙古国境内某金铜矿大型调蓄水池工程,介绍了HDPE土工膜在大型调蓄水池中作为防渗衬垫和浮动盖板的设计方案,对防渗和防蒸发需要考虑的因素进行了说明,同时给出了土工膜有关计算的方法,以期能为蓄水池设计提供一套新颖的设计理念。 Combined with the project of a large copper reservoir in Mongolia, the design scheme of HDPE geomembrane as a seepage-proof liner and floating cover in a large storage basin was introduced. The factors that need to be considered in seepage prevention and evaporation prevention Description, at the same time gives the geomembrane calculation method, with a view to provide a set of innovative design concepts for reservoir design.
