Design criteria of rock socked pile in South Korea

국내 암반에 근입된 현장타설말뚝의 설계기준 수립

The Design criteria are different from one another due to the different engineering properties of rock in the every nation. Most of the test results of the rock-socketed piers were loaded two times of the design load capacities because they would be used in the foundation of the bridge or the building. So we have much difficulties in study of the load capacities of the rock-socketed piers by the test result in Korea. When we design the rock-socket piers, every designer uses the different formula, and makes different results. Recently the demand of the large bridges and the huge buildings has been increased. The adequate design criterion of the rock-socketed pier is urgently needed to design them reasonable. In this paper we analyzed the various design criteria and proposed the adequate design criterion which is based on the test results of the rock-socked piers in Korea.
