EVALUATION METHOD OF COEFFICIENT OF EARTH PRESSURE AT REST IN PILE OR SAND COMPACTION PILE DRIVING GROUND AND EVALUATION METHOD OF COEFFICIENT OF EARTH PRESSURE AT REST IN THE SAND COMPACTION PILE ITSELF OF THE SAND COMPACTION PILE DRIVING GROUND

摘要

PROBLEM TO BE SOLVED: To provide a method for evaluating a coefficient of earth pressure at rest of ground into which a pile or a sand compaction pile is driven, which allows the proper evaluation of an increase in the coefficient of the earth pressure at rest of the ground due to the driving of the pile or the sand compaction pile, and enables the coefficient of the earth pressure at rest to be properly and simply applied to a design.;SOLUTION: In this method, an electric static cone penetration test is carried out at a representative point in an execution area; after the obtainment of cone end resistance before the driving of the pile or the sand compaction pile, a test for obtaining the cone end resistance after the driving is carried out by driving a plurality of test piles or test sand compaction piles; and the coefficient of the earth pressure at rest of sandy ground is calculated for evaluation from test results.;COPYRIGHT: (C)2003,JPO
