Back analysis for pile bearing capacity using Static Load Test result / Nurharnani Hassan

Hassan, Nurharnani (2005) Back analysis for pile bearing capacity using Static Load Test result / Nurharnani Hassan. [Student Project] (Unpublished)


In Civil Engineering point view, the important aspect during design stage is to obtain the cost effective design or to avoid over and under estimate design on pile bearing capacity. Chin Method is one of the simplest way and widely used in Malaysia in order to estimate the ultimate pile bearing capacity. This study has chosen Chin Method because this method was accurate and easy to understand. The result of this study found that in Penang, the piles foundation design could be considered as under estimate, and a few of them are reasonable and over estimate. The under estimate pile design has Puitimate based on Chin Method larger than 2x design load. This resulted in wastage of material and ineffective cost utilisation for the project. This study also focus on determine the status of pile deduced from design assumption and manufacturer’s specification. Based on this study, it can be concluded that most test piles in Penang were experience geotechnical govern while some of them are under structural govern and pile overloaded. This study also concern about failure analysis in term of excessive settlement. Excessive settlement was not the major cause in pile failure. Only 3 projects in Penang were having excessive settlement. JKR failure criteria were used to compare between settlement values from Static Load Test with standard value from JKR criteria.
