Prediction of Monopile Driveability under Vibratory Driving Using Wave Equation Analysis
Prediction of Monopile Driveability under Vibratory Driving Using Wave Equation Analysis
One of the most well-known tools used in the industry, particularly for impact hammers, is the GRLWEAP software, which uses one-dimensional wave equation analysis to simulate the penetration process of a single pile into the ground. This paper presents the results of a case study on the prediction of vibratory monopile driving using GRLWEAP. The simulation of the driving process and the validation using measured data of a real offshore monopile during installation are described in detail. The simulation with GRLWEAP with CPT data from the site investigation show good agreement with the measured data from the installation. In the further part of the paper, the influence of the hook load on the driveability of the pile is investigated. Advantages and limitations of the method are discussed in detail.
