Soil Mechanics and Foundation Engineering Mcqs

This set of Civil Engineering Multiple Choice Questions & Answers (MCQs) focuses on “ Soil Mechanics and Foundation Engineering ”. These Mcqs are chosen from a collection of most authoritative and best reference books on Civil Engineering. Our aim is to prepare an individual for competitive exams like NTS, GAT, ECAT, University and College entrance exams, Jobs and interviews. One should practice our MCQS to assimilate Soil Mechanics and Foundation Engineering comprehensively.
