Geological Site Analysis and Soil Properties Report

This report provides a comprehensive geological analysis, examining various aspects of a site. It identifies metamorphic, intrusive, and extrusive rock types, along with the geological processes such as faulting and metamorphism. The report also addresses soil properties, including well-graded soil and compaction, crucial for geotechnical engineering. It explores the impact of soil loading and consolidation. The analysis includes the identification of specific geological features like unconformities and the sequence of geological events. The document also explores the impact of soil conditions on structural integrity, and the role of effective stress. The report provides insights into the importance of these factors in civil engineering projects.

Question 1
a) Metamorphic rocks because they are hard and strong and highly weather
resistant rocks.
b) Rocks like metamorphic, igneous and sedimentary rocks may occur at
site, all of these may cause problems while excavation or during bore tests
for checking soil properties.
c) Three examples of geological activity that are evident at the site are
mentioned below:
a. The Mohenjo-Daro is the evidence for geology site because it is
ancient place dig by geologists only.
b. Harappa is an evidence place because
c. Taxila is an evidence place because
d. Fossils dig by the geologists is also an evidence, which tells us
about past.
d) Hydrological forces are subject of investigation and engineering the
landscape visibility is also one of that process in which due to water cycle
process landscape occurs.
e) Fault infill suggests that as they are filled by soil, it decreases the
turbulence for site.
f) As earthquake comes on the plates of rock moves, the movement also
occurs between the sides of the fault.
g) They are sedimentary rocks, formed when mineral particles, fragmented
rock particles are transported by wind, water or ice.
h) It causes rock disintegration by breaking, grinding, crushing, they are
going to expand and contract possibly cause structural deterioration.
i) Micro-diorites are the types of igneous rocks, they are formed when
magma (melten matter) cools sufficiently to solidify.

Question 2
a) The intrusive and extrusive events evident in the area are:
a. Intrusive: Granite, Diorite
b. Extrusive: Phyllite, sandstone, shale, mudstone.
b) Two unconformities evident in the area are:
a. Mica Schist; and
b. Gnesis.
c) Structural geological process evident from the map is that the process of
fault occurs in the map.
d) Metamorphic processes appear that the process of low-grade
metamorphism takes place.
e) In the north-west side does the metamorphic grade increases.
f) The difference in the sedimentary rock-type to the north of the map
suggests that they are the top of the surface.
g) The approximate strike of the dipping layers is 120degree.
h) The sequence of geological events that may have occurred in this area are
firstly shale, slate and mudstone moves, then gradually granite and diorite
moves at a slow place.

Question 3
a)
a. Coefficient of uniformity
Coefficient of curvature

b. Sample is not well graded
c. Well-graded soil is very essential for projects of geotechnical
engineering because there is no void in this type of soil and is
water impermeable soil.

QUESTION 4
a)
b)
c)

d)

e)

QUESTION 5
a) Compaction
a. Compaction is the process by which solid soil particles are packed
more closely together by mechanical means.
b. It is a rapid process.
c. Reduction of aid voids
d. Is it artificial process
b)
c) For greater compaction, dry density increases and optimum meistitic
content decreases.
d)
