Mechanics can be found everywhere in our life, mechanics of materials is the most widespread, seepage mechanics as an important branch of mechanics is also indispensable。Seepage in soil has the branch of saturated soil and unsaturated soil play a crucial role。Seepage of water permeability as an important part in highway construction and plays an important role in the municipal construction, is fundamental to the principle of design and construction engineering application technology。Water quicksand, as a new technology is now widely application in engineering。Seepage has a significant impact in the real project, it is like a double-edged sword, we how to use, to exert its maximum value, this is worth thinking about!Keywords: saturated soil and unsaturated soil highway construction municipal water permeability quicksand
