Although under the action of the short-time heavy rainfall the rainwater infiltration depth has not arrived at the slope initial underground water level, and the under ground water level has not significantly increased, but engineering data shows that slope slide caused by this type of rain has often happened which brings great loss to the society.
For this reason, based on the two dimensional saturated-unsaturated seepage theory in this paper, corresponding calculation of the seepage field under the action of short-term heavy rain was done in order to deeply analyse the influence of the slope transient water pressure distribution and change situation on soil slope stability in this kind of special climate conditions, which can provide the reference for the engineering practice.
Therefore, when used finite element software to do numerical calculation, considering the rainwater infiltration meets its darcy flow equilibrium principle in rainfall condition, the filtration equations was described as the seepage models of slope section 2d unstable flow problems[5]; considering the permeability coefficient of geotechnical engineering is related to the unit saturation degree, the permeability coefficient change rule of saturated-unsaturated analysis used the Van Genuchten model to describe.

Introduction Slope is an important part of engineering construction,it’s inevitable to transform the lithospheric surface during the process of developing basic construction & transportation construction,then form a lot of man-made slopes[1].With the rapid expansion of economic construction,there are many slope engineerings during the process of developing basic construction & resource exploitation.The height and the difficulty of construction become larger with the development of construction scale.While the slope engineering is controled by topographical and geological conditions,the stability problems become increasingly prominent.Especially the emerging of slope of foundation pit during urban construction,the slope stability study of foundation pit has become a hot & difficult point[2-3].

Engineering costs are nevertheless still remain high as the preparation of input data and the interpretation of results require a significant amount of time.
TMW provides 4 material models; one elastic model and three most popular non-linear material models used in geotechnical engineering, which are Mohr-Coulomb, Hoek-Brown and Drucker-Prager.
Such dramatic reduction in engineering time provides the user much more time to undertake numerous preliminary analyses, carry out parametric studies for various patterns, and investigate for potential problems during construction.
