In addition, the author has deduced groundwater seepageequation of roadbed of setting different egis slope, and analysed the height of soakage line inside of roadbed of setting different egis slope. It is concluded that no matter what roadbed is in steady seepage or unsteady seepage, it is more avail to drain of roadbed using better penetration materials (such as no-fines concrete etc) than using weak penetration material s.

另外,推导了设置护坡的路基的地下水流方程,分析了设置不同护坡时路基中的浸润线高度及其变化,认为无论路基处于稳定流还是非稳定流,用强透水材料作护坡比弱透水材料作护坡对路基地下水的排出更为有利。

As to multi-layer reservoirs,each layer can be divided into three areas:area of gravel-packing,area of perforation and area of radial flow.Each area has its own governing equaiton and the solution is expressed by Green function.The well bore pressure and layer-rate is given through Green function in Laplace space.The pressure drop and skin factor isobtained also in each area.

根据多层砾石充填完井的流特点,将每个产层在径向上分成3个区域,即砾石充填区、射孔区、地层径向流区,每个区域有各自的流方程,对n层油藏有3n个流方程,将每个区域的方程用Green函数来表示,由各层的Green函数得到井筒混合压力、分层压力及分层产量在Laplace空间上的解,最后得到每层各区域的压力损失、表皮系数以及井底压力和分层产量与时间的变化关系。

The difficulty of leachate treatment is not only the organic pollutants of high concentration in the early leachate, but also the high ammonium concentration and low C/N ratio of the old leachates.
