Important Guidelines On The Finite Element Modelling Of Micropiles

This paper highlights essential considerations for FE modeling of pressure-grouted micropiles.To accurately simulate micropile behaviour, it is crucial to consider both its composition and construction method.The use of pressurized grout for micropile construction has a considerable effect on the behaviour of the pile and the surrounding soil.In addition, micropiles generally acquire a high elastic modulus, owing to the high percentage of steel reinforcement adopted.Not considering this installation procedure and/or the high elastic modulus would lead to underestimated predictions of the micropile load capacity.A brief introduction is also given to the Increased Ks Method, which was extensively used in the literature for FE simulation of the effects of the micropile installation process.
