AEJ - Alexandria Engineering Journal, 2021 The pile-soil stress ratio (PSSR) is the key to the design and construction of geosynthetic-reinforced pile-supported (GRPS) embankments. However, the computation models for the PSSR which takes account of the effect of consolidation settlement of soil among piles (SAP) is not complete.

Study on Load Transfer Mechanism of Pile-Supported Embankment Based on Response Surface Method
Applied Sciences, 2022 Based on the improved three-dimensional finite element model, this paper studies the load transfer mechanism of pile-supported reinforced embankments. The model uses an elastic medium to replace the soft soil subgrade, which reduces the calculation depth

Analysis of Load Transfer Law of Short Pile-Net Composite Foundation for High-Speed Railway
Shock and Vibration, 2022 Although pile-net composite foundation has been widely used in the construction of high-speed railway, load transfer characteristics of its structural system during the filling of roadbed are seldom studied, so field studies are conducted in the Gan-Long

Simplified analytical solution for stress concentration ratio of piled embankments incorporating pile–soil interaction [PDF]
Railway Engineering Science, 2021 AbstractPiled embankments have been extensively used for high-speed rail over soft soils because of their effectiveness in minimizing differential settlement and shortening the construction period. Stress concentration ratio, defined as the ratio of vertical stress carried by pile heads (or pile caps if applicable) to that by adjacent soils, is a ...

A Research on the Pile-soil Stress Ratio Range of the Vibroflotation Pile Composite Foundation [PDF]
Proceedings of the 2016 International Forum on Energy, Environment and Sustainable Development, 2016 The pile-soil stress ratio refers to the ratio between the stress of the pile top and the average stress of the soil among piles. It is an important parameter reflecting the operation status of the composite foundation, as well as a significant index to calculate the bearing capacity and the settlement of the composite foundation.
