He additionally held the posts of Head of Civil Engg. Engineering College, Jodhpur. During his instructing profession of about 36 years, he guided a lot of analysis college students. Punmia has authored greater than hundred papers, monographs and technical studies revealed in numerous Indian and Foreign Journals. He had been advisor to numerous authorities, semi-government and personal organizations. He can also be a prolific author within the area of Civil Engineering. Arun Kumar Jain : He is gold medallist at each B.
Apart from instructing, he has guided greater than a dozen college students at M. Soil Mechanics and Foundations By B. LearnCreative crew attempt to Helping the scholars and others who can not afford shopping for books is our goal. Thank you. Our planet Earth has a median radius of km and a imply mass density of 5. The mantle consists of two components, higher mantle and decrease mantle. The higher mantle is strong rock whereas the decrease mantle is molten rock. Above the higher mantle is the crust, which can be as a lot as 50 km thick within the continental areas and as little as 7 km thick in oceanic areas.
The crust and a part of the higher mantle, about km thick, make up the lithosphere. Below the lithosphere is the asthenosphere, which is about km thick.
The lithosphere is fragmented into about 20 giant plates—giant blocks of rocks—that slide in opposition to and transfer towards, away from, and below one another above sizzling molten supplies within the asthenosphere. The principle governing the actions of the plates is named plate tectonics. Sediments are strong fragments of inorganic or natural materials ensuing from the weathering of rocks and are transported and deposited by wind, water, or ice.
Igneous rocks are shaped from magma molten rock supplies emitted from volcanoes that has cooled and solidified. The warmth and pressures which might be concerned in forming sedimentary rocks are low compared to these for igneous rocks. Their look and texture are variable.
No melting takes place, so the unique chemical composition of the unique rock stays unchanged. The rock texture typically turns into coarser-grained.
Eight km. The sediments that comprise sedimentary rocks could also be bonded cemented collectively by minerals, chemical substances, and electrical attraction or could also be free. Examples of clastic sedimentary rocks are sandstones shaped from sand cemented by minerals and located on seashores and sand dunes; shales shaped from clay and dust and located in lakes and swamps; and conglomerates shaped from sand and gravels on the backside of streams.
Chemical sedimentary rocks are minerals similar to halite rock salt , calcite, and gypsum which have been shaped from components dissolved in water e. Organic sedimentary rocks are shaped from natural supplies similar to crops, bones, and shells. Coal is an natural sedimentary rock shaped deep within the earth from the compaction of crops.
Soils are shaped from the bodily and chemical weathering of rocks. Physical weathering entails discount of measurement with none change within the unique composition of the dad or mum rock and it is explained in details in Soil Mechanics and Foundations.
Because excessive settlement can make structure fail for efficient working. So, various types of foundation like spread foundation, foundation action, well foundation e. When it is required to make a safe structure having a slope or there is less space to construct a structure then the structure is required to retain deep under the soil. A Pavement is a hard crust made by compaction of soil for the purpose of providing a smooth and strong surface and transmitting the load of traffic and vehicles.
The behavior of pavement may swell, shrink under the various condition of loading environmental effect which causes the failure of the transportation system. Hence, to this kind of problem, we must know of soil mechanics. Earth dams are a huge structure made of soil as a construction material built for creating water reservoirs. To construct it we must have knowledge of consolidation, slope stability, effects of seepage, and consequent settlement as well as compaction characteristics of the soil.
Soil mechanics is an important branch of engineering mechanics applied in civil engineering to predict the behavior of soil. All structures have the same foundation, i. Thus, a study of the behavior of its chief component becomes prudent for every civil engineer. Soil Mechanics And Foundations is a must-have for every civil engineering student. It deals with topics beyond soil characteristics, including retaining wall, foundations, and piers.
Soil Mechanics and Foundations By B. Punmia, Ashok Kumar Jain, Arun Kumar Jaink first published in and running into its Sixteenth Edition, has been thoroughly revised, updated and enlarged.
This book is intended to present currently accepted theories, design principles and practices of soil mechanics and foundation engineering. The book provides sufficient material ranging from simple to very complex for undergraduate and postgraduate courses. At the end of each chapter, latest problems from various central competitive examinations has been solved to enable the student to test his reading at different stages of his studies.
Soil Mechanics and Foundations : Dr. Punmia : It provides a comprehensive understanding of soil characteristics and properties. It even contains experiments to help students gain a practical insight into soil mechanics. With all structures having earth as its common foundation, its essential that students of civil engineering understand this main component.
