| 摘 要： | 基于多孔介质渗流力学理论建立了垃圾填埋气体传输过程的动力学模型,采用Laplace变换对气体传输渗流场控制方程进行近似解析求解,得到了填埋气体非线性渗流的压力分布规律.由不同时间填埋气体压力随水平距离分布计算结果看出:随时间的增长,压力曲线变缓,压力增大.

| Abstract: | A dynamic mathematical model of the landfill gas transport process has been established,which is based on the theory of mechanics of porous seepage,and the approximate analytic solutions of the control equation of the landfill gas seepage field are accomplished by the Laplace transformation method.Thus,the gas pressure distribution law of the nonlinear seepage has been presented.The pressure distributions of the landfill gas that go with the horizontal distance in different time show that: the pressure curve becomes slowly,and there is a stepping increase varying with time in gas pressure. |
