Lecture 1 : Introduction [ Section 1.2 : Methods of Site Exploration ]
1.2.4
Information Extraction from site investigation topography
General topography of sites which affects foundation design & construction.
Ex:-surface configuration & waterways.
Location of buried services
Ex:-Telephone lines, Water lines Power lines ssss
General Geology of the India with particular reference to the principal geological formation underlines the site.
Previous history & use of the site i/c information of any defects and failures of structures built on the sites.
Any special features such as possibility of earthquake, folding, seasonal swelling etc.
Availability and quality of local construction materials.
Detailed record of soil and rock strata & ground water condition within the zone affected by foundation loadings & of any deeper strata affecting site conditions in any way.
Design data which comprises strength and compressibility characteristics of different strata.
Results of chemical analysis on soil or groundwater to determine possible deleterious effect on foundation structures
