LOADING TEST METHOD AND LOADING TEST DEVICE FOR COMPOSITE REINFORCEMENT GROUND

摘要

PROBLEM TO BE SOLVED: To provide a loading test method and a loading test device for composite reinforcement ground, which enable high-precision measurement of a load acting on a pile alone concurrently with measurement of a test load acting on both the ground and the pile.;SOLUTION: A hydraulic jack 8 comprising a load cell 9 makes a test load applied to a loading plate 2 having a through-hole 2A formed in a central part. The test load is partially transferred to an upper end surface of a pile P, which is positioned within the through-hole 2A, via a high-tension bolt 5, a pressing plate 4 and a load cell 3 from the loading plate 2. The test load acting on both ground and the pile is measured by the load cell 9, and a load acting on the pile P alone is measured by the load cell 3.;COPYRIGHT: (C)2014,JPO&INPIT
