Discussion of “Numerical Analysis of Reinforcement Tensile Forces in Reinforced Foundation over Soft Soil” by Xiaopeng Guo, Qi Gu, Wan Zhang, Hongqiang Hu and Hao Zhang, Published in Geotechnical and Geological Engineering
摘要
This discussion article presents a critical appraisal of the developed model in the Guo et al. (Geotech Geol Eng 43:329, 2025a. https://doi.org/10.1007/s10706025-03289-7) on geosynthetic-reinforced soil foundations (GRSFs) overlying the soft soil layer. The calibrated model is used to perform a comprehensive parametric study to examine the effect of various influencing factors on the distribution and variation of reinforcement tensile force. Almost all cases of influencing factors it is observed that the tensile forces in the reinforcement layers near the footing edges are the maximum and the maximum tensile forces increase with the depth of embedment of the layer. These two observations are under discussion here as the previous studies in geosynthetic-reinforced soil foundations show that the maximum tensile strength is generally higher in the top layer as compared to the bottom layers and the maximum tensile forces are mobilized below the centre of the footing. Hence a proper explanation may be required for the observed variation and distribution of tensile force in the present study.
