For huge influence on their stabilities and performances. Seepage

For a construction
project, it often encounter with the groundwater. Seepage can be known as the continuous
motion of water in soils, it usually cause a critical issues to the construction
in civil engineering. Seepage is the application of groundwater hydraulic and
we can find the discharge of seepage through and beneath the structure. It will
cause the uplift pressure under the structure and also the foundation and
piping failure, hence, it is very important to understand and design a seepage
control.

Seepage
control is the most important consideration in the stability of dams, natural
slopes and levees. The excavations for structures, cut slopes, open-pit mines,
tunnels, and shafts and side-hill fills. It is well recognised in geotechnical
engineering practise such as dams, slopes, landslides, underground spaces and
so on. It is like groundwater seepage has a great influence and effect on the
deformation and stability of soils, rocks and geotechnical structures. Seepage
control measures of grout and drainage curtains in the rock foundation of
concrete dams are common problems concerned and considered by the civil
engineers. Seepage control is critical for maintaining the stability and safety
of the civil engineering work in construction site.

A large number
of engineering measures have been widely taken for seepage control in
geotechnical and geo-related environmental engineering practices. Seepage flow
through soils, rocks and geotechnical structures has a huge influence on their
stabilities and performances. Seepage control is a critical technological problem
in engineering practices.

The
physical mechanisms are associated with different types of engineering measures
for seepage control are investigated and examined from a new point of view
within the framework of continuum mechanics and an equation based
classification of seepage control mechanisms is proposed according to its roles
in the mathematical models for seepage flow, included the control mechanisms by
coupled processes, boundary conditions, initial states and hydraulic
properties. The effects of each mechanism on seepage control are illustrated
with examples in hydroelectric engineering and radioactive waste disposal.
Therefore, the reasonability of classification is demonstrated.

Suggestions
on optimization design and performance assessment of the seepage control
systems in geo-engineering is provided. The suggested procedure as well as the
steps taken would serve as a important guidance line for cost-effective control
of seepage flow in different types of engineering practices. Understanding the
physical mechanisms and their corresponding numerical modelling approaches of
engineering measures for seepage control is obviously of paramount importance
for optimization design, construction, safety assessment, and operation of a
seepage control system.
