Prediction of shaft resistance of bored pile in limestone formation

Piles socketed into limestone are commonly used in Malaysia especially for deep foundation of high rise building at Kuala Lumpur area. The heavy structural loads are transmitted to the bedrock through the contact surface between concrete and the limestone. However much uncertainty involved in the se...
