Parameters determination methods and project validation of hardening soil model with small strain stiffness based on finite element method.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The hardening soil model with small strain stiffness is a valuable tool for predicting the deformation of support structures during the excavation phase of construction projects. The stiffness parameters of the model, which are dependent on technically complex and costly tests or estimated through specific proportionate, may exhibit some discrepancy between the analyzed results and the project monitoring data in certain aspects. In light of the findings from the conducted analyses and studies, the new concepts of reference in-situ overburden pressure and reference in-situ void ratio are proposed with the objective of enabling the determination of the essential parameters required for HSS model through the utilization of the results of the current geotechnical tests, which are of high popularity and economy. Additionally, the article offers recommendations for determining other parameters, providing a summary of a systematic approach to determining the necessary parameters for the hardening soil model with small strain. Ultimately, a comparison and verification of the finite element method results of a deep excavation project with the monitoring data demonstrated that the research outcomes exhibited sufficient numerical analysis accuracy and practical applicability.
