Pile group effect is crucial for correct estimation of the hydrodynamic force on a pile within a pile-group foundation of sea-crossing bridge during earthquakes unlike the case of single isolated pile. A numerical calculation model considering fluid-structure interaction under the combined loads of ...
(1) A simple calculation formula to predict the group efficiency parameter of pile group under dragload is built by assuming an effective influence area. Pile group arrangement, embedment length to diameter ratio of piles, pile spacing, soil properties such as angle of internal friction, density ...
Based on the degradation model of subgrade reaction,a new method is proposed for calculation of pile bent with all straight piles.Considering effect of pile group and non-linear deflection,the internal force and deflection calculated by this method agrees better with data from practice than that of...

A main observation was that the response in the loading of the center pile as a part of the group in effect was a reloading of the pile. The response at first loading of the pile as a single pile was considerably less stiff. Similar to the authors' work, the references mentioned above...
5) group pile foundation 群桩基础 1. Based on a special shaped single pylon cable-stayed bridge on the foundation of group piles, the program for FEM calculation is adopted for dispersion of the beam grillage system at the footing and for structural analysis and calculation of the group ...
a simplified calculation approach for average settlement of pile groups is obtained.The nonlinear relationship between the pile tip load and the settlement at the pile tip,and the nonlinear settlement induced by the skin friction can be taken into account,as well as the pile shaft compression.The...
Calculation of engineering quantity The construction process for the SCP group mainly involves determining the pile location, preparing the cement slurry, spraying the slurry to form a cement-soil pile, inserting the pipe pile, planting steel bars in the pipe pile cores, pouring the pipe pile core...
