Importance of Geology in the field of civil engineering in Nepal
Importance of Geology in the field of
civil engineering in Nepal
Nepal is a mountainous country. The
Himalayan range is result of collision of Tibetan and Indian plates. So, the
region is the most active tectonic zone. This area is widely known for its
complex structural deformation. Due to the reason, Nepal is suffering from
different types of geo hazards and instabilities. The earthquakes in 1990 B.S
magh 2, in 25 April 2015 (7.8 Richter scale) and in 12 may 2015 (7.3 Richter
scale) and its continuous post shocks indicates there is potential of large
scale earthquake. The loss of property and life we bear during these
earthquakes show that we are not concern about the natural disaster and our
construction are not safe. Thus for safe and stable construction to resist such
phenomenon geology is important. Similarly, the most part of Nepal contains the
mountains, hills which have different types of rock. For the construction
through the hill the stability of slope is necessary which depend upon the
nature of rock, thus study of rock is necessary. Generally, in monsoon season
we suffer from the problem of flood especially in terai region. Geology helps
to mitigate the effects of flood on civil engineering construction by proper
treatment. Beside these, there are numbers of rivers, glaciers etc and for the
construction f dams, bridge it is necessary to know about river morphology.
Thus for safe, stable and sustainable engineering project geology is important.
Importance of geology in civil engineering
The successful construction and running of civil engineering
project depend upon the fact that how they treat the geology of the site. If
they have deal with the geology of the site carefully then structure will be
stable, else may fail due to various causes. Some of importance of geology in
civil engineering are mentioned below:
1. Geology
provides a systematic knowledge of construction materials, their structure and
properties.
2. The
knowledge of Erosion, Transportation and Deposition (ETD) by surface water
helps in soil conservation, river control, coastal and harbor works.
3. The
knowledge about the nature of the rocks is very necessary in tunneling,
constructing roads and in determining the stability of cuts and slopes. Thus,
geology helps in civil engineering.
4. The
foundation problems of dams, bridges and buildings are directly related with
geology of the area where they are to be built.
5. The
knowledge of ground water is necessary in connection with excavation works,
water supply irrigation and many other purposes.
6.
Geological maps and sections help considerably in planning many engineering
projects.
7. It help to treat the geological structures which has influence in engineering structure
suitably that may be located nearby construction site.
8. It helps to manage the local resource properly for
safe stable and economical design and construction of a civil engineering
projects.
