Calculate the pile capacity for a precast reinforced concrete pile 0.25×0.25 m with a length of 10 m that consists of two layers, a medium and a stiff clay (Fig. 8.13). Sign in to download full-size image Figure 8.13. Example calculation. Solution: For medium clay layer: Su=45 kPa,...
Model tests were conducted to investigate the behavior of a special-shaped pile group (2脳1, and 2脳2) and a single pile under uplift loading. A theoretical method was developed to estimate the ultimate uplift capacity of the special-shaped pile group based on a unified composite failure ...
Calculation Method of Comprehensive Effect Coefficient for Lateral Bearing Capacity of Pile Group Liu Jinli Institute of Foundation Engineering China Academy of Building Research Beijing More Information Abstract Series of prototype and models very close to prototype were tested for lateral bearing ...
The undrained shear strength and effective overburden stress profiles are the two factors that most affect the pile axial capacity calculation. The wide variety of sampling techniques and the potentially large scatter in the strength data from the various types of laboratory tests complicate appropriate...
GroupUnsaturated claySuctionBearing capacityIn this study, an attempt is made to investigate the load transfer in pile groups constructed in saturated and unsaturated soil using aluminum model piles of 20×20 mm in cross section and 200 mm in length with six group configurations, single, 2×1, ...
group foundation under the lateral load located near slope for the first time to describe the interaction of ultimate soil resistance around pile in the same row.Based on the presented method, the finite difference program is adopted to assess the response of a two-pile group in sloping ground...
According to the above calculation and processing of strain data obtained from the model test, a total of four groups of pile bending moment distribution figures are obtained when the displacement of pile is 2 cm, 14 cm, 16 cm and 17 cm. Figure 13 The curves of bending moment of pile ...
On the basis of the bottom uplift pile model built in section "Establishment of the finite element model", to study the influence of various factors on the bearing capacity of the bottom uplift pile, in this section, different finite element software calculation models were built by changing dif...
It is found that there are uncertainties in measurement and also in calculation, as the measured pile capacities are affected by the uncertainty in measurement error. On the other hand, the predicted pile capacity from the equation is very sensitive to the undrained shear strength values which als...
For long pile group anchors ( L / d =30), the isolation spacing appears to be at a spacing of about 4d, 6d and 8d for B / d =1, 2 and 3, respectively. The analytical model of limit equilibrium method has been proposed to predict the net uplift capacity of pile group anchors. ...
