Behavior of Large Geotextile Mat Cofferdam with a New Arrangement of Geotextile Reinforcement Stiffness Lying on Soft Sediments
TLDR
In this paper, a new arrangement of geotextile reinforcement stiffness for large geotectile mat cofferdams was proposed, which often suffers from the failure of the bottom layer mat.Abstract:

Effect of Boundary Conditions on the Mechanical Behavior of the Geogrid–Soil Interface
TL;DR: In this article, a series of pullout tests were carried out on high-density polyethylene (HDPE) geogrid-reinforced coarse sand, and the boundary reduction coefficient (BRC) was introduced to establish the relationship between rigid and flexible boundary for the design of the structure.

Analyzing Different Methods to Model a Marine Mattress on a Partially Submerged Slope
TL;DR: In this paper , the stability of a partially submerged marine mattress was analyzed in five potential ways including modelling as (1) a high-strength material, (2) an unreinforced layer of revetment stone, (3) a layer of geosynthetic material enveloped by a specific manufactured geo-grid, and (4) a surcharge load with the same unit weight as the revetMENT stone layer.
