Engineering Characterization of Bedrock and Design of Rock-Socketed Bored Pile in Eastern Thailand

Abstract

This study aims at evaluating and improving design methods of rock-socketed bored piles in Eastern Thailand. The properties of the bedrock at Sriracha district in the Eastern of Thailand are investigated, including physical, index, and engineering properties. Empirical correlations among the obtained index and engineering properties of the bedrock are derived and proposed, which are qu-Is(50), qu-HR, and t-HR, although the strength of these relationships are quite low. The empirical equations for a rock-socketed bored pile design for the studied area are proposed by verifying them with the dynamic pile load test results. The obtained equations of side and tip resistances are compared with those proposed by various researchers and some comments are also made.
