Study on ElastoPlastic Analysis of Tunnel Model with Permeation Grouting By Bentonite [ ]


The construction of structure on weak ground often requires the soil to be improved in order to ensure the safety and stability of surrounding structure. Due to this poor construction activity the building can face many problems like settlement. The low bearing capacity of foundation bed causes shear failure and excessive settlement. sanaz sayehvand et.al, (2012) vol-17 To overcome these problems many ground improvement techniques are used. Ground improvement techniques are used to strength sub soil properties in terms of bearing capacity james joyco et.al, (1992), shear strength, settlement characteristics and drainage. It consist two techniques which can be selected according to loading condition, Nature of weak soil.
