Mandro and Chase
Geotechnique , throughout their 30 years of activity, have maintained a strong and active research and
development department. The group experts led by our mentor and managing director
using considerable databases have
carried out numerous research projects, some in collaboration
with well-known universities and research institutions.
Of these projects, over 30
papers have been published in well-known professional journals and international
conferences.
presented in
A list of these publications is presented herein.
Numerous other topics are available in-group archives
and available by permission.
Among the main
projects studied and developed in Mandro's R&D
department we offer the following:
|
Remedial work for reduction of differential settlement in heavy
structures:
This
method, which is developed by Mandro was
first used to in a
large
cement silo which had differential settlements
of about 65
centimeters.
Using
specially designed steel chains,
the underlying soil was sawed off in thin
layers, such that the structure was tilted
back to an almost
horizontal position.

|
Collapsible Soils:
Extensive study
on understanding the behavior of collapsible soils
has been done at Mandro's R&D department.
A mathematical model has been developed, using the stability of
large voids or macro-pores in the soil body, and taking into account
parameters like degree of saturation, void ratio,
article sizes, cementation agents, and
loading characteristics.
Numerical simulation is possible by implementing this model.
The brown areas in
the Iran map shows the existence
of the
collapsible soils.

|
Partially Saturated
Soils:
Another research area
that has been studied by us is the behavior of partially saturated
soil. The experimental and mathematical
studies show that the preferential orientations
of macro-pores, which are influenced by the type of deposition, affect the volumetric
strains of soils at various saturation ratios.
