“…These results demonstrate the importance of considering Mechanism S when evaluating pile loading within tunnel-piled structure interaction problems, even for the relatively flexible building considered in this study (more rigid structures will have a greater effect on pile head load redistribution, as demonstrated by Franza et al (2021b)). Mechanism S is currently not considered within standard tunnel design risk assessments (e.g.…”

“…Mechanism S is currently not considered within standard tunnel design risk assessments (e.g. Mair et al (1996); Schoor et al ( 2021)), though recent work by Franza et al (2021b) has provided a rational approach for incorporating building stiffness within a computationally efficient two-stage model for soil-pile-structure interaction analysis. and FEA tests at a tunnel volume loss of V l,t = 3%.…”

“…The behavior of single pile is analyzed using existing theory and simulation method. Franza A. et al (2021) investigated the interaction between soilpile-structure caused by vertical loads and tunneling [9]. Model results for piles subjected to vertical loads compare well with the field and other analytical models to confirm the reliability of the model.…”

The driving of pile into the ground is one of the important tasks of construction works and especially for new buildings in big city. Difficulties in driving piles for new construction will adversely affect the foundations of neighboring and adjacent building. This research proposes a measure to assess the state of conduct of the pile driving process using a nonlinear Finite Element Method (FEM). Manuscript using Plaxis 3D Foundation analysis software for an existing building with reinforced concrete pile foundation with foundation tower size 2.0 m x 2.0 m on 4 piles with a cross-section of 0.3 m x 0.3 m, length 10.0 m; foundation bearing a load of 1000 kN. Then press the reinforced concrete pile size 0.3 m x 0.3 m, pile length 10.0 m, pressing position 0.5 m from the edge of the existing foundation, pressure 500 kN. The results of the analysis showed the effect of the adjacent pile process to the stress and strain of the neighboring building foundation in cramped land for construction conditions. In order to provide solutions to overcome difficulties for the adjacent building be effective. The effective stress in the existing reinforced concrete pile foundation without adjacent is -273.7 kN/m 2 , but when it is interlocked, it is -3490.0 kN/m 2 . After pressing the piles, the horizontal displacement of the existing piles is 10.2 mm and a bending moment of 48.6 kNm occurs.

“…Meanwhile, numerous researchers had studied the influence of stress history on the friction coefficient and cohesiveness at the pile-soil interface using loading-unloading systems. A. Franza et al [20] investigated the sinking process of hydrostatic piles in sandy soils utilizing indoor half-pile model tests, revealing the movement patterns of the soil at different locations around the piles. It was well known that the method of installation of pile foundations had a great influence on the behavioral characteristics of the piles.…”

A field pile loading test was carried out on the Peshawar–Karachi Motorway (PKM) project in Pakistan to show the settling mechanism of bored pile foundation in pulverized soil and the force characteristics of frictional resistance at the pile-soil interface. The changes in pile lateral frictional resistance and pile settlement during the loading-unloading process of test piles were measured and analyzed, as well as the load-settlement distribution characteristics of test piles in different soil layers, the distribution of test pile internal forces, and the changes in pile-soil relative displacement. It was established that there was considerable deterioration of pile lateral frictional resistance and residual deformation of pile tip displacement throughout the test pile load-settlement process, and the association between the pile-soil interface frictional resistance and pile-soil relative displacement was addressed. The results reveal that the frictional resistance at the pile-soil interface is directly connected to the nature of the soil layer, with a positive connection between the natural density, specific gravity, compression deformation, and the plastic index under immediate load, and a negative correlation between the natural moisture content, compression coefficient, and settlement variations after unloading. The load-settlement of the pile rose in a non-linear proportion during the loading-unloading operation, with a maximum settlement value at the pile top of 8.14 mm and a residual deformation at the pile bottom of 1.94 mm. The frictional resistance of the pile perimeter was distributed non-linearly throughout the pile depth, and the frictional resistance of the pile-soil interface was severely deteriorated at an embedded depth of 15 m, with the degradation degree of the silty soil layer being significantly smaller than that of the silty clay soil. The relative pile-soil displacement was positively linked with the lateral frictional resistance of the pile under the same load, and the correlation coefficient in silty soil was much greater than that in sandy soil.
