Abstract
Domestic high-rise buildings booming, the foundation piles are widely designed and engineered. However, the foundation bearing capacity such as the ultimate friction and bottom limit point bearing strength may be calculated according to theory or empirical formulas applicable. In order to verify the actual ground conditions with calculations, test piles shall have the results which are able to feedback structure design parameters to the pile design and engineering. Thus, the actual bearing load of the piles of various sizes will be available for actual site work. On the other hand, it can be checked whether the pile design were reasonable or not. In addition, we may use test pile to verify the foundation design approach.
Test piles might not be essential works for foundation design and engineering unless it is requested per building regulations or cost analysis per Design Architect. Our study is to assess the value engineering of test piles. After pile test, the safety factor might be lowered for foundation engineering and consequently achieve cost saving of foundation works.
Ultra-high-rise buildings shall conduct the test piles to achieve more safe and economical design. Test pile results need not to meet the design value. Furthermore, the test pile results are consistent with soil foundation conditions. It is analyzed to assess the human factors and clarify the responsibilities and reduce the potential opportunities for engineering test pile dispute. Actual case studies collected and the current construction methods piles investigated are based on major domestic methods applicable and controversial cost-benefit analysis.
