Shaking table test and numerical simulation of free field in sand-sawdust mixed soil

Experimental Study of the Dynamic Characteristics and Microscopic Mechanism of Lightweight Soil Modified with Expanded Polystyrene and Sisal Fibre

“…Figure 10 shows that Ed/Edmax − εd continued to increase with increasing sisal admixture and then tended to be stable. The Hardin-Drnevich model [24] cannot describe its curve variation trend well, according to the studies of Zhuang Xinshan [9] and Hou Tianshun [23] on the modified model. In this study, the improved Hardin-Drnevich curve model, i.e., the Darendeli model [25], was used; it is expressed as the following: To further analyse the trend of the maximum value of the dynamic modulus of elasticity of the specimen [22] and the maximum value of E dmax , the inverse of the dynamic modulus of elasticity and E dmax curves were established, as shown in Figures 8 and 9.…”
