EFFECT OF GROUTED PILE BASE QUALITY ON VERTICAL BEARING CAPACITY CHARACTERISTICS OF EMBEDDED PILES

Abstract

The vertical bearing capacity of piles by embedment method is considered to be affected by the strength and stiffness of the grouted pile base, but there are few reports on this subject. Therefore, various experiments were conducted to understand the effects of differences in the quality of the grouted pile base on the bearing capacity. As a result, it was found that sand and gravel does not significantly affect the bearing capacity even if they are mixed in the grouted pile base, but clay and block of clay decreases if they are mixed more than a certain amount.
