摘要
从环境保护的角度出发,针对灰水溶质运移污染地下水的问题,应用研制的混合防渗材料作为防渗层,通过有限元程序模拟贮灰场的实际运行条件,进行了贮灰场静力计算分析。结果表明:防渗层在灰场运行期间,沉降变形、应力水平及应变均不大,可保证防渗层及贮灰坝的结构安全性。
It＇ s important to build fly ash storing sites to prevent fly ash from polluting air, ground and water. But improper design, construction and operation would result in serious pollution problems. In this paper, the influence in the stress state of impermeability layer was simulated by Finite Element Method （FEM）. The results show that the settlement, deformation, stress level and strain of impermeable layer are less in the course of fly ash filling.
