Deflection Measurement of Bored Pile Body With Steel Bar Meters in the Lateral Load Test



This paper presents a lateral load test conducted with a service bored grout pile. In this test, 15 pairs of steel bar meters were mounted in the pile body. The equipment not only measures the section moments of the pile body, but also measures the deflections and rotations of the pile body, which are measured by inclinometers traditionally. A comparison between the deformation near the pile head measured by the steel bar meters, and the one measured by four dial gauges proved that it is valid to use steel bar meters to measure the lateral deformation of pile body during lateral loading tests. Moreover, the results are very precise before the lateral load exceeds the elastic limit, which was determined as 120 kN in the present study.
