Before starting of any structure like multistory building or
other structure more loaded firstly we have to make subsoil exploration in
order to obtain information used in design and construction of foundation , since foundation transmit all load from structure
to the soil .
Subsoil exploration is the process of obtain soil
stratification at a given site or determining the layers of natural the soil
deposit that will underlie the proposed structural and their physical property,
this process done because engineers need to know information that will help
then in determining the nature of soil at the site and its stratification and
in Selecting the type and depth of foundation
suitable for a given structure.
nature of the soil at site
Engineers also their need to know information for evaluating
the load-bearing capacity of the foundation, information help them in estimating
the probable settlement of a structure ,location of ground water table, the
depth and nature of bedrock ,investigation of safety of existing structural, suitability
of the soil and degree of compaction.
Subsoil exploration of structural are divided in three phase
such as Collection of Preliminary
Information, Reconnaissance and Site Investigation, this phase of site
investigation provide reliable, specific and detail information about the soil
and ground water condition of the site, and consist of Planning; making
test boreholes; collecting soil samples at desired intervals for visual
observation and laboratory tests.
In determination
of the number of boring there is no hard-and-fast rule exists for
determining the number of borings are to be advanced. For most buildings, at least one boring at each corner and one at
the center should provide a start. Spacing can be increased or
decreased, depending on the condition of the subsoil for more information
