This book is about the behaviour of engineering soils and simple geotechnical structures such as foundations and slopes and it covers most of the theoretical geotechnical engineering content of a degree course in civil engineering. The book is aimed primarily at students taking first degree courses in civil engineering but it should also appeal to engineers, engineering geologists and postgraduate students wishing for a simple and straightforward introduction to the current theories of soil mechanics and geotechnical engineering. Although it deals specifically with soils and soil mechanics many of the theories and methods described apply also to rocks and rock mechanics.--- Ushbu kitob muhandislik tuproqlari va poydevorlar va qiyaliklar kabi oddiy geotexnik tuzilmalarning xatti-harakatlari haqida bo'lib, u qurilish muhandisligi bo'yicha daraja kursining nazariy geotexnik muhandislik mazmunining ko'p qismini qamrab oladi. Kitob birinchi navbatda qurilish muhandisligi bo'yicha birinchi darajali kurslarni o'tayotgan talabalarga qaratilgan, ammo u tuproq mexanikasi va geotexnika muhandisligining hozirgi nazariyalari bilan oddiy va tushunarli kirishni xohlaydigan muhandislar, muhandis-geologlar va aspirantlarga ham murojaat qilishi kerak. Garchi u tuproq va tuproq mexanikasi bilan bog'liq bo'lsa-da, tavsiflangan ko'plab nazariyalar va usullar tog 'jinslari va tog' jinslari mexanikasiga ham tegishli.
