Numerical Analysis - Numerical Simulation Project:
Use  GeoStudio to numerically simulate the deformations and stability of a  road constructed on the clay foundation. The foundation consists of 2.5 m  desiccated and over-consolidated clay (at the top) and 7.5 m slightly  over-consolidated soft clay stratum. The clay stratum is on top of the  coarse sand and gravel with a high hydraulic conductivity so that the  static pressure head at the top of gravel is 8.5 m. water table is at a  depth of 1.5 m
It is  assumed that the pore-water pressure in the underlying granular material  will not change due to the road construction. Also, assume that both  the upper crust and the underlying clay are simplified to be homogeneous  isotropic soil layers. Consider the following assumption along with  Modified Cam-Clay (MCC) constitutive model in SIGMA/W for the soft clay.

The  volumetric water content function is not used for saturated conditions  but is nonetheless required. Therefore, consider a volumetric water  content of 0.3. In addition, assume the following for the desiccated  clay crust.

The  road is an unsealed road with width and height of 14m and 1.8m,  respectively. The material used for the road construction over a period  of six days are coarse and sand gravel. There is no embankment for the  road. All the relevant road material properties are listed in table  below:

Note: Make reasonable assumptions if needed and state your assumptions clearly in your report.
Task:
Prepare a report with the following components:
a) Model Geometry (Max. 1-page image)
b) Model Materials (Max. 1-page text)
c) Boundary conditions and analysis type (Max. 2-page text/graph/image)
d)  Discuss the changes in settlements, pore-water pressures and horizontal  deflections at the depth of 10 m over next five years after  construction. You need to include the graphs of excess pore-water  pressure (during the road construction and long- term monitoring), long  term settlement of the original ground surface, horizontal deflections  (during the road construction and long- term monitoring).
The  report must be submitted in the current MS Word file including the  answers to the above questions. You should also upload your Geostudio  into a Google drive and add the link to the report.
