EFFECT OF VARYING NON PLASTIC FINES CONTENTS ON UNDRAINED SHEAR STRENGTH OF SOIL
Creators
Description
The flow failures of the alluvial sandy ground cause catastrophic damage such as tilting of structures, floating up of structures, permanent later displacement of ground. In order to quantify the tendency of flow characteristics of sandy soils, a simple and reliable concept of steady state strength approach has been used. To evaluate the same, total ten tests are conducted with relative density varying as 30% and 45% and for same effective consolidation pressure of 120kPa. It was observed that with increase in equivalent granular state parameter the residual shear strength reduces till threshold fines content and later on increases.
