Comparison between ultimate pilecapacity ofbored piles determine using analytical method, numerical method and pileloadtest along Sentul - Batu Caves Double Track Project

The objectives ofthis project is to compare various method of bearing
capacity determination (analytical method, numerical method andpile loadtest) as well
as to back calculate soil parameters based on pile load test results.
Basically the mainproblem is howto derive the parameters from the early
stages of construction in orderto maximize benefits. Besides that through load test
resultswhat parameters controlthe results fromthe actual on-site results can be found.
How much load is actually transferred to thepile will befound outand try to work out
through it with this testby analytical methods onwhat empirical formula to bebased.
The scope of study includes studying all pile test results along with the
parameters which altersthe result of eachas wellas to analyse the results by the
analytical method through failing anactual piletest andthencomparing the actual
values withthe one beinggenerated bythe test values. Otherscopes would include find
out the parameters that are themost important and try to reduce some of it through the
numerical methods.
The methodology of the project would include to firstly, collecting and
summarized all soil data pertaining to the site and characterize soil layering system
along the track. Secondly, collect all pile test results and characterize response of pile
load tests. Thirdly, reduce thenumber of parameters thatare being considered so that the
analysis will not be too complicated. Fourthly, calculate ultimate pile capacity based on
analytical method, numerical method and pile load test results .Fifthly back calculate
soil parameters based onpile load test results and lastly analyse andsynthesize results as
well as draw conclusions.
The findings that coincide with the projectare the LoadSettlement Curve which
coincides withthe PileDynamic Analysis and the Maintained LoadTest results can be
used to becompared with theresults from thepile which has failed. Besides that,
through thedeflection of thecurve, one is able to know the parameters that are involved in determining the curve's shape and whether it complies with the theoretical curve. The
last finding would be that every pile has different soil characteristics which may increase
or decrease the pile's Bearing Capacity.
Keywords for this project would include Bearing Capacity, Bored Piles, Pile
Load Tests, Soil Investigations, and Cone Penetration Tests.
