摘要

Dynamic load test methods of single piles in vertical direction have been developed. In a vertical dynamic load test, signal matching analysis is carried out to identify appropriate soil resistance parameters. A static load-settlement curve of the tested pile is then calculated using the identified soil parameters. The dynamic pile load test method requires less time and cost compared with the conventional static pile load test. Hence, the authors have been developing a dynamic pile load test method of single piles in the horizontal direction. In this paper, the method of dynamic horizontal pile load test including loading and measuring systems and an analytical method is described first. Then, the validity of the proposed horizontal dynamic load test is examined and discussed through three case studies where dynamic horizontal load test and static horizontal load test were carried. It is concluded that although the proposed method still has a room for improvement, the proposed dynamic horizontal load test method is a promising approach to estimate static horizontal load vs horizontal displacement of a tested single pile.
