TY - JOUR PY - 2022// TI - Study on guardrail post behavior located on organic soil using simplified experimental and numerical methods JO - Soils and rocks A1 - Manaviparast, Hamid Reza A1 - Araújo, Nuno A1 - Cristelo, Nuno A1 - Miranda, Tiago SP - e2022077921 EP - e2022077921 VL - 45 IS - 2 N2 - For the purpose of road safety, it is vital to reduce the severity of road accidents and increase safety around the roadway area by deploying guardrails. In case of a car crash, a guardrail post must be deformable so that such restraint is not too abrupt due to the occupant's sensitivity. Soil type influences on the guardrail post behavior have been a somewhat unfounded variable due to the high soil heterogeneity and challenging interpretation of its real implications on the safety of guardrail systems. Since little attention is concentrated on evaluating the guardrail post behavior through simplified procedures, this article aims to provide a simplified experimental and numerical approach to study the behavior of guardrail posts located on organic soil.

RESULTS of laboratory and in-situ tests indicated that guardrail posts behavior located on organic soil depends on section orientation, driving depth, and loading speed. To confirm and compare the in-situ tests, simplified numerical simulations through Plaxis 3D software were carried out, and data from numerical modeling approved the accuracy of in-situ results.
