Effect of over-consolidation characteristics of foundation soil on shallow plate loading test
WANG Zhi-hui
Abstract：In order to research the influence of shape and size of loading plate on the shallow plate loading test for the over-consolidated soil, the shallow plate loading test for the coarse-grained soil at the bottom of foundation pit was carried out through adopting the loading plates with different shape and size.The results show that a flat section appears near the preconsolidation pressure on the load-settlement curve.When the diameter of round loading plate is the same as the width of square loading plate, the characteristic value of bearing capacity of foundation soil, which is obtained with the round loading plate, is larger.With increasing the size of loading plate, the characteristic value of bearing capacity of foundation soil gradually increases and tends to be convergent.Compared with the experimental results of loading plate with the diameter between 0.1m and 0.3m, the experimental results of loading plate with the diameter between 0.6m and 0.8m have better stability.
