Helical Piles Embedded in Expansive Soil Overlaying Sandy Soil

Al-Khawarizmi Engineering Journal, 2017
In this study, the behavior of square helical piles models (5×5) mm2 embedded in expansive soil bed overlaying a layer of sandy soil was investigated. The sand layer 200mm thickness was compacted into four sub layers in a steel container with diameter ...

Evaluation of Helical Pile Performance in TRcM for Soft Ground Improvement: Insights from Field Test and Application

Advances in Civil Engineering
The tabular roof construction method (TRcM) is an alternative to open-cut and cover tunnels commonly used in constructing underground structures. The open-cut tunnels often lead to traffic congestion and ground settlement, especially in densely populated

Assessment of Experimental Data and Analytical Method of Helical Pile Capacity Under Tension and Compressive Loading in Dense Sand

Buildings
This study presents the results of axial tension (uplift) and compression tests evaluating the capacity of helical piles installed in Shahriyar dense sand using the UTM apparatus. Thirteen pile load experiments involving single-, double-, or triple-helix

Optimization and field validation of laterally loaded helical piles for solar farm infrastructure projects

Scientific Reports
Several studies have extensively explored the axial (uplift and compressive) behavior of helical piles, while lateral behavior—an equally critical aspect in the design of foundation systems— remains relatively uncharted.

Investigation of monotonic behavior of different-pattern helical pile groups in sandy soils

International Journal of Geo-Engineering
Nowadays, due to the rapid progress of countries in constructing various structures, cost and the environment have become highly important. These structures must be considerably strengthened and improved, as they are built on land and water.
