Abstract

Anchored soldier piles and lagging walls (Berlin Wall) is one of the modern methods to excavation stabilization in recent years. The aim of this paper is the study of behavior of deep excavation by anchored soldier piles using numerical modeling in PlAXIS 3D software. For this purpose the effect of surcharge loading, mechanical properties of soils and length of anchors on deformations and distribution of tensions are studied. In this study, the soil type and the depth of excavation is selected clay and 15meters, respectively. The obtained results show that the surcharge load, mechanical properties and anchor length have a significant effect on the behavior of the excavations. With increasing of cohesion and friction angle of soils, magnitude of deformations and stresses decrease. But increasing of the anchors length has not impressive effect on deformations and stresses.
