초록
In this paper, the Coefficient of Subgrade Reaction was analyzed from the data which were the results of lateral pile loading tests and pressuremeter tests on construction sites. The prediction method with N-value was compared with lateral pile loading tests and the results of lateral pile loading tests were compared with the prediction method considering diameter of a pile. Also, the results of lateral pressuremeter tests were compared with those of lateral pile loading tests. As a result, consideration for a diameter and lateral deformation of a pile was needed when the coefficient of horizontal subgrade reaction is presumed. Therefore, a formula which is taking into account the allowable deformation of a pile was suggested from lateral pressuremeter tests in this study.
