Using of jet grouting piles reinforced with central bars for low retaining walls

Abstract

In the retaining geotechnical structures it is important that the structural element must take not only axial forces, but bending moments too. The jet grouting piles are widely used when retaining walls and foundations of the structures are made. In most cases these piles are reinforced with rigid profile without evaluating the piles material strength. Malinin, A.G and Malinin, P.A (2004) proposed a method for the calculation of jet grouting piles reinforced with the central bar and acted by bending moment. The method of the bending moment calculation with more realistic assumption is suggested this article. This method is safer than propose Malinin, A.G and Malinin P.A (2004). Piles diameter and material strength are very important for the bending moment calculation. The reinforcement with central bars requires less metal than reinforcing with rigid profiles. The reinforcement with central bars is sufficient for retaining walls made using jet grouting technology.
