Friction bearing capacity

In the scope of the paper studying the pile group effect in case of multilayered foundation, especially the effect of porous, medium-tight sand layers in the foundation on the load bearing capacity and subsidence of friction piles, the following issues are clarified: (i) coefficient of pile group in multi-layered foundation, with sand and clayey soil layer; (ii) distribution of forces along the pile shaft; (iii) effect of pile group on settlement of the pile group.

In this paper, a computational approach using a combination of the upper bound theorem and the bubbleenhanced quadrilateral finite element (FEM-Qi6) is proposed to evaluate bearing capacity factors of strip footing in cohesive-frictional soil. The new element is built based on the quadrilateral element (Q4) by adding a pair of internal nodes to solve the volumetric locking phenomenon.

In this study, construction sequence and prediction of axial bearing capacity of M-pile on cohesive soil were introduced. M-pile analysis used with outer diameter of 318.5 mm and thickness of 12.7 mm. The analysis results show that the ultimate bearing capacity prediction of M-pilein soft clay soil considerably increase compared with bored and cast-in-place piles with the same diameter and depth thanks to multiple blades welded along the pile shaft.
