“…Pier 7 (an interior pier) of the bridge was selected for the live load test because a static load test on instrumented test piles (7-11) had been performed in 2016 close to this pier, providing valuable reference for the understanding of the foundation response to the live load in the present study. In addition, most of the in situ tests (standard penetration tests and cone penetration tests) had been performed close to Pier 7, and the test results can be found in (8,9,(11)(12)(13). The test site consists mainly of poorly-graded sand and gravel mixtures.…”

In this paper, we report the results of a live load test performed on the Sagamore Parkway bridge over the Wabash River, Indiana. The seven-span concrete bridge was constructed from 2016 to 2018 to replace the old, east-bound bridge. The main goals of the live load test were: (i) to study the transfer of the live loads from the bridge pier to the foundation elements and the distribution of live loads among the individual piles supporting the bridge pier; and (ii) to verify the assumptions (e.g., regarding the pile cap resistance) made in bridge foundation design. For these purposes, one of the interior piers (Pier 7) of the bridge and the fifteen pipe piles supporting it were instrumented with vibrating-wire strain gauges. With the bridge temporarily closed to traffic, the live load test was performed by parking twelve loaded triaxle trucks at specific locations on the bridge deck near Pier 7 in March 2019. The truck loads were applied in seven stages, simulating the driving of several trucks over the bridge pier. The settlement of the pier was measured using a digital level during the live load test. The data from the strain gauge readings were processed to produce the history of load distribution within the cross section of the pier and among the piles in the pile group during the seven stages of the live load test. The soil in contact with the pile cap carried about half of the total live load.

“…Many scholars at home and abroad have conducted field tests [1][2][3] and indoor tests [4][5][6][7], combined with numerical simulation, to study the force state of the pile body in the process of pile jacking. Doherty et al [1] carried out field tests of open pile and studied the stress during pile jacking.…”

“…Zhang et al [2] studied the main influence and effect of soil clogging through field tests, and studied the change rule of pile end resistance. Han et al [3] conducted a slow-maintaining static load test for closed and open steel pipe piles driven side-by-side, and studied the difference in resistance between the two piles. Paik [4] studied the influence of soil plugs on the bearing capacity of open-ended pipe piles, and quantified it with an incremental filling rate.…”

Model Test of Jacked Pile Penetration Process Considering Influence of Pile Diameter

et al. 2021

In order to investigate the influence of different diameters on pile end resistance, pile side resistance, pile axial force and pile force transmission law of jacked pile penetration, two pairs of embedded sensitized microfiber grating sensors were installed by slotting the pile body. The pile-jacking process of static-pressing viscous foundation soil with different diameters of closed-tube model piles was successfully monitored. The test results show that the pile pressure, pile end resistance and pile side resistance of the two test piles increase linearly with the increase of pile depth. When the pile jacks, the final pressure of the test pile TP1 is higher than that of the test pile. TP2 is 31% higher, pile end resistance is 18% higher, and total side resistance is 57% higher. The results show that increasing the pile diameter can significantly increase the pile side resistance; under different penetration depths, the pile side resistance is from top to end. Continuously exerted, the axial force of the pile body decreases with the depth of the pile and the slope of the distribution curve of the axial forcegradually decreases. At the maximum penetration depth, the axial force of the pile TP1 is 18% larger than that of the test pile TP2; As the depth increases, the unit side resistance at the same penetration depth gradually decreases, that is, the side resistance has a “degradation effect”; at the end of the pile jacking, the percentage of the pile end resistance to the pile force exceeds 50%, that is, the pile end resistance bears most of the load. This research can be used as a reference for the study of pile driving mechanism in clayey and layered clayey soils.

“…The studies mentioned above mainly concentrated on solid piles. It is also an undeniable truth that many types of pipe piles are increasingly adopted for their good performance [13]. As is known to all, the major distinction of the pipe pile compared with the solid pile lies in the formation of the soil column in the pile cavity during pile installation [14,21,27,61,62].…”

This paper is concentrated on the influence of the inner soil on the torsional vibration of a pipe pile embedded in inhomogeneous soil. First, the soil-pile system is divided into several segments in the vertical direction in accordance with the layered properties of the soil and the inner soil-filled height. Then, the outer (inner) soil is further subdivided into finite vertical ring-shaped zones in the radial direction to simulate its radial inhomogeneity due to the construction disturbance. The dynamic equilibrium equation for each outer (inner) soil zone is solved, and the outer (inner) soil-pipe pile dynamic interaction is obtained. On this basis, the dynamic equilibrium equation for the pipe pile is solved by the Laplace transform and the recursive method is employed to derive the analytical solutions for the complex impedance and amplitudefrequency response of the twist angle at the pile head. The reliability of the proposed solutions is verified by comparisons with other solutions. Finally, a sensitivity analysis is performed to portray the influence of the inner soil on the torsional vibration of the pipe pile.
