ABSTRACT

Nowadays construction is centered around urban environment where there will be a lot of civilians and buildings surrounding the environment. The use of conventional types of pile installation machine will create noise and vibration which is sometimes a nuisance to the public and the vibration from the pile installation process may damage the nearby buildings. This disadvantage will definitely create a lot of public complaints during the execution of construction and contractors will face a dilemma where the local authority would issue fines and much worse, imposing a ‘stop work order’ to their project.

The study will focus on the reliability of Jack-in method in assessing pile bearing capacity. Analysis on comparing jack-in data will be with the result from pile bearing capacity obtained from pile test on the same point is done through variation of pile capacity in time, length over diameter ratio and factor of safety criteria. 11 data obtained from local authorities were interpreted and compared.

From the analysis done, it shows that the jack-in method is acceptable in the reliability of confirming the pile bearing capacity.

In this research, the researchers will examine the relationship between the fluctuation of housing price in the United States and the macroeconomic variables, which are

The water content variation causes the change in undrained shear strength and these changes have an impact to the friction capacity and adhesion factor of pile foundation.. This

He applied the technique on single pile, pile group and piled raft to reduce the size of the entire soil stiffness matrix.. In this technique, the pile is treated as

In pile instrumentation particularly, obtaining distributed strain profile is important when analysing the load- transfer and shaft friction of a pile, as well as detecting

In this research, soil test reports of different locations of Dhaka city were collected, and the bearing capacity of the soil was calculated by Terzaghi's method based on a

Prediction of pile capacity is performed, however, the statistical analyses and evaluation of the prediction methods is conducted based on the results of several friction

The main objective of thesis is to study the behaviour of integral abutment bridge under temperature variations and seismic loading and investigate variation of
