Optimum design of pile foundations

For the optimum design of pile foundations, the determination of allowable load should take both the material strength and the geotechnical characteristics of the site into consideration. Through survey of previous construction records in Korea, it was found that most of the design is overconservative and in some cases the design load was higher than the constructed quality. Proper analysis making use of WEAP and monitoring of pile driving by PDA have been proved to solve most of the prevailing problems. In addition, the time effect in the evaluation of pile bearing capacity has the must significant effect and should not be ignored in the pile design.
