1 ª Œª Œ 27ƒ 4C Á œ pp. 293~304 ª x mw - Shear Behavior Charateristics of Drilled Shaft - Rockmass Interface Using Direct Shear Test Under Constant Normal Stiffness Condition Á Á z Jeong, Sang SeomÁWoo, Sang YoonÁSeol, Hoon Il Abstract This paper described the theoretical shear strength function proposed to predict the shear behavior of pile-rock joint under constant normal stiffness condition. The quantified values of rock socket roughness were determined through previous studies and this study. Constant normal stiffness direct shear tests were carried out to quantify the shear behavior characteristics based on major influencing factors of shear behavior such as asperity angle, unconfined compressive strength, initial confining stress. Based on CNS test results, this paper proposed the shear strength function simulating the major influencing factors of shear behavior of pile-rock joint, including asperity angle, unconfined compressive strength and elastic compression displacement as well. The proposed function was verified by the CNS test result performed to artificial rocks molded to describe regular asperities, granite and gneiss. Through comparisons with the CNS test results, it is shown that the shear strength function by this study is in good estimation with the general trend observed by the tests. Through comparisons of the maximum shear strength between the domestic criterion of shaft resistance and shear strength function of this study, it was shown that the maximum shear strength by the function of this study considerably increased than the strength by the doemstic criterion along with the higher asperity angle and initial confining stress.
