28. Numerical modelling of field vane shear test in sensitive clay

Author

Kundu, Pritam

Abstract

The undrained shear strength of clay is one of the key parameters in geotechnical design, which can be determined from laboratory or field tests. The disturbance of soil samples during sampling, transporting, storing and trimming could influence the laboratory test result, which could be significantly high for sensitive clay because the structure of the soil might be changed. Therefore, the field vane shear test (VST) is commonly used to determine the undrained shear strength of sensitive clay. Although the test is relatively simple, the interpretation of the VST results is challenging, as the failure mechanisms are still not well understood and cannot be observed in the field. Therefore, numerical simulation might be a viable option to examine such mechanisms. Some attempts have been made previously using Lagrangian-based finite element (FE) analysis but not could model the complete process, because large shear strains develop along the thin shear plane, which causes mesh distortion and numerical issues. In the present study, VST is simulated using an Eulerian-based FE approach. In this approach, the Eulerian material (soil) flows through the fixed mesh; therefore, the simulation can be continued for a large penetration and rotation. A nonlinear strain-softening and strain-rate dependent soil model for the undrained shear strength of sensitive clays is incorporated in the FE simulation. The first set of simulations is performed for only one element of thickness (i.e., two-dimensional conditions) by applying rotation to a rigid vane. Three-dimensional simulations are then performed by penetrating the vane to the desired depth, followed by a rotation. The rotation initiates the formation of a rounded square-shaped failure block which turns into a circular one after the peak torque. The penetration of the vane can significantly disturb the surrounding sensitive clay and thereby reduce the maximum torque during rotation. The extent of disturbance depends on several factors, such as blade thickness, soil sensitivity, and post-peak strength degradation parameters.

Abstract

The project work was designed to investigate the phytochemical and selected pharmacological activities (antidiarrheal, analgesic, neuropharmacological behavior and anthelmintic) of leaves of Sanchezia nobilis. Hook. F. (Family: Acanthaceae). From its phytochemical analysis we found the presence of reducing sugar, combined reducing sugar, phenolic compounds, tannins, flavonoids, carbohydrates, gums, steroids, alkaloids, glycosides and terpenoids. In vivo antidiarrheal activity was substantiated by prolongation of latent period and decrease in total number of stools. The extract produced 62.49% and 74.01% decrease in stool count at the doses of 250 and 500 mg/kg body weight respectively while the standard drug Loperamide decrease in stool count was found to be 87.05% at a dose of 3 mg/kg body weight. The leaves extract produced 32.7% and 41.78% inhibition of writhing at the doses of 250 mg/kg and 500 mg/kg body weight respectively while the standard drug Diclofenac Na was found to be 74.23% at a dose of 25 mg/kg body weight. The extract showed dose dependent CNS depressant activity by reducing the locomotors activity. Higher dose of this extract (500 mg/kg body weight) comparing with standard Diazepam exposed sedative effect potentially. The extract exhibited concentration dependent anthelmintic activity against Paramphistomum cervi using Albendazole (15 mg/mL) as standard. The paralysis occurred between 9.00 to 83.91 min and death occurred between 11.33 to 86.33 min which were comparable to standard drug Albendazole. So, the present study concluded that the extract is fortified with significant antidiarrheal, CNS depression and anthelmintic activity and moderate analgesic activity. [ABSTRACT FROM AUTHOR]
