贮灰场灰水渗漏特性及防渗措施的研究

Water Leakage Characteristic and Counter Measures in Ash Storage Yard

以中砂、细砂、粉砂、砂质粉土和粉质粘土为贮灰场底部包气带的主要代表土层，试验研究了贮灰场灰水在包气带土层中的渗漏特性。防渗试验表明，压实后的粘性土层和上工膜具有良好的防渗性能，且简便易行、无污染。结合各土层的具体情况，提出了相应的防渗措施。

Using medium-sized sand, fine sand, silts, silt clay as primary representative soils in aerated zone under ash storage yard, the water leakage characteristic in aerated zone was experimented. The results of leakage prevention tests indicated that pressed gummy solum and earthwork film have good performance of preventing water leakage. They are simple, practicable and no pollution.
