“…Pile is a civil engineering structure with a long history, which has been used for more than 14,000 years. With the development of science and technology, piles have been made of cast-iron sheets, steel, cement, concrete, and reinforced concrete [1][2][3]. With the rapid development of engineering construction, pile foundation has been widely used in housing construction, bridge wharf, and managing geological disasters.…”

Considering the limitations of terrain and engineering expenses, antislide piles are sometimes arranged in polylines. Studies show that this arrangement adversely affects the mechanical characteristics of antislide piles. However, there is no in-deep understanding of this issue and the structural design and calculation method of this arrangement have not been discussed in relevant standards. Aiming at resolving this shortcoming, the polylines pile arrangement is studied in this article to provide a scientific basis for designing and calculating antislide piles. To this end, the cantilever pile is taken as the research background, and the soil arching effect between piles is taken as the research object. Then the performances of the single-row polyline pile layout and straight line pile layout are analyzed in the Dawanjiang landslide and the results are verified from the aspects of the landslide reinforcement and the influence on the antislide pile structure. The obtained results show that the polyline pile layout is disadvantageous to the safety of the antislide pile structure, and the soil arch between piles under the polyline pile layout condition is not uniform. Meanwhile, it is found that as the polyline pile layout angle increases, the stress concentration appears at the “inflection point.” Under this circumstance, the soil arch between piles is not uniform, and the stress concentration intensifies.

“…Pile foundations have been in use for thousands of years [ 1 ] while concrete piles have become particularly widespread in the last 50 years. However, the growing use of larger diameter and longer piles has resulted in increased concern over the integrity and quality of cast-in-place foundation piles.…”

The integrity of cast-in-place foundation piles is a major concern in geotechnical engineering. In this study, distributed fibre optic sensing (DFOS) cables, embedded in a pile during concreting, are used to measure the changes in concrete curing temperature profile to infer concrete cover thickness through modelling of heat transfer processes within the concrete and adjacent ground. A field trial was conducted at a high-rise building construction site in London during the construction of a 51 m long test pile. DFOS cables were attached to the reinforcement cage of the pile at four different axial directions to obtain distributed temperature change data along the pile. The monitoring data shows a clear development of concrete hydration temperature with time and the pattern of the change varies due to small changes in concrete cover. A one-dimensional axisymmetric heat transfer finite element (FE) model is used to estimate the pile geometry with depth by back analysing the DFOS data. The results show that the estimated pile diameter varies with depth in the range between 1.40 and 1.56 m for this instrumented pile. This average pile diameter profile compares well to that obtained with the standard Thermal Integrity Profiling (TIP) method. A parametric study is conducted to examine the sensitivity of concrete and soil thermal properties on estimating the pile geometry.

“…Timber has been used as a piling material for several thousand years and continues to be used to this day (Ulitskii, 1995). Typically these types of piles are used in northern Canada and Europe primarily due to the low cost and the requirement of raised foundations due to permafrost conditions.…”

Experimental Study of Hollow Fibre Reinforced Polymer Piles in Soft Clay

In this thesis, a research program aimed at investigating the performance of fiber reinforced polymers (FRPs) piles in soft clays is presented. The main goal was to determine and characterize the interface shear strength properties of carbon and glass FRPs against clays, identify the influence of material selection and fiber orientation, and compare these results to the performance of traditional piling materials such as steel and concrete. FRP materials have experienced a surge in interest during the recent decades due to their favourable properties such as resistance to corrosion and degradation in comparison to steel and concrete particularly in harsh or contaminated soil conditions such as waterfront applications. The first experimental program investigates interface shear strength using a direct shear box apparatus. The second experimental program expands on the previous work through conducting static pile load tests under axial and lateral loading conditions of small scale FRP and steel piles in soft clays. The results of this experimental testing indicates that for all of the FRP interfaces tested in both element and small scale pile load tests, the interface shear strength is higher or at least on par with steel interfaces. Material selection and orientation had a limited role on pile performance as most FRP piles presented similar interface shear strength results. The findings presented in this work show that the FRP piles are a viable alternative to steel piles. Further studies in the form of full scale pile load tests are needed in order to corroborate the results presented herein. III AWCKNOWLEDGMENTS I would like to thank my supervisor Dr. Mohammed Rayhani for his support and guidance through the completion of my graduate work. His insight has helped me greatly on the start of my professional career. I would like to thank my colleagues and friends
