Question $1[4$x$7=28$ Marks$]$

$1\mathrm{.}1.$ What are the different in situ test methods available for geotechnical

investigations, and how do they differ in terms of applicability and accuracy?

$1\mathrm{.}2.$ What are the minimum requirements in terms of the amount and depth of

investigations necessary for reliable geotechnical assessments?

$1\mathrm{.}3.$ How do influence depths affect the required depth of investigation in

geotechnical testing, and what factors should be considered in determining this

depth?

$1\mathrm{.}4.$ Can you distinguish between various in situ test methods and discuss their

respective applicability in different ground conditions?

$1\mathrm{.}5.$ Which ground parameters can be derived from different in situ test methods,

and how do these parameters contribute to geotechnical analyses and

designs?

$1\mathrm{.}6.$ What are the basic laboratory testing methods commonly used in geotechnical

engineering, and how do their results inform site investigations and analyses?

$1\mathrm{.}7.$ When establishing minimum requirements for geotechnical investigations,

which guidelines or standards should be consulted, and why are they

important?
