In this paper, we focus on the importance of conducting the necessary tests either
field or laboratory in order to obtain realistic values for soil hydrodynamic parameters
allowing the best result to simulate the actual situation of any engineering
facility.
The importance of this research highlights in earth dams and dikes which have great
importance to economic, environmental and human. It is necessary to be complete
accuracy when creating a mathematical model to study stability of these structures. From
here comes the need to calculate these parameters rather than extracted from engineering
codes, that we will use them to simulate the effect of long rainfall on the distribution of
water content in the Hweez dam soil and hence its stability. We will build a mathematical
model for dam using PCSiWaPro® depending on transition flow chart. concerning that,
hydraulic conductivity and volumetric water content in the soil are functions of pore water
pressure. These equations with their functions give a smooth transition of the studied
model where the saturated state is considered as a special case of the used equations.
This research study the cause failure earth dams After that it show the
more important problems which dams exposure.
During its construction and compassingthe importance causes of this
case and how we can processing it , and show also the necessar
y of
earth dams observerand the necessary reportsto showing that the work
of dam is good.
The research also discusses the analysis of earth dam using the Geo
slope program.
We have chosen many parameters as total stresses, vertical strain , and
pore water pressure to study change of this parameters with elevation
in the upstream , downstream , and core of dam and draw the requisite
graphsgraphs to compare this design values with reading of observer
devices to be sure of typical work of dam.
Finaly we showing the results and suggest many recommendations.
