Numerical study on the lateral behavior of pile groups in Toyoura sand using the hypoplastic constitutive model [PDF]
Scientific ReportsA pile group under lateral loading is a complex pile‒soil-pile interaction problem. In this study, numerical analysis was used to investigate the lateral behavior of pile groups arranged in a 3 × 3 configuration with varying piles spacings.

Numerical investigation of laterally loaded pile groups at the crest of slopes [PDF]
Scientific ReportsPile group foundations are widely used to support tall structures on both level and sloping terrain. However, predicting the lateral response of pile groups near slopes remains challenging due to complex soil-pile interactions that differ significantly ...

Numerical Modelling of Axially Loaded Helical Piles: Compressive Resistance [PDF]
E3S Web of Conferences, 2021 Helical piles are foundation systems used to support compression, tension, and lateral loads. However, this type of piles was used around the world for more than 25 years. Its behavior, especially in Iraq, is still unknown and scare. The present study is

Adaptive Optimization Method for Piled Raft Foundations Based on Variable Pile Spacing
Applied Sciences, 2023 Stricter control of the differential settlement is always required in important buildings more than in ordinary buildings. It becomes a necessity to find a simple and efficient optimum design method for pile foundations in terms of performance and economy.

Effect of pile spacing on the thermal performance of thermo-active pile groups
Symposium on Energy Geotechnics 2023, 2023 Thermo-active piles differ from conventional piles in a way that they have pipes embedded within them, which allow a carrier fluid to circulate through and exchange heat with the ground, in order to provide low carbon heating and cooling. Sustainability targets, such as the Merton Rule, which requires a proportion of the energy demand of the building ...
