Soil Mechanics and Foundations by Muni Budhu

Author :Muni Budhu


Soil Mechanics and Foundations by muni budhu  is intended to present the principles of soil mechanics and its application to foundation analyses. It will provide you with an understanding of the properties and behavior of soils, albeit not a perfect
understanding. The design of safe and economical geotechnical structures or systems requires considerable experience and judgment, which cannot be obtained by reading this or any other textbook. It is
hoped that the fundamental principles and guidance provided in this textbook will be a base for lifelong
learning in the science and art of geotechnical engineering.
The goals of this textbook in a course on soil mechanics and foundation are as follows:
1. To understand the physical and mechanical properties of soils.
2. To determine parameters from soil testing to characterize soil properties, soil strength, and soil
3. To apply the principles of soil mechanics to analyze and design simple geotechnical systems.

When you complete studying this textbook you should be able to:
• Describe soils and determine their physical characteristics such as grain size, water content, and
void ratio.
• Classify soils.
• Determine compaction of soils.
• Understand the importance of soil investigations and be able to plan a soil investigation.
• Understand the concept of effective stress.
• Determine total and effective stresses and porewater pressures.
• Determine soil permeability.
• Determine how surface stresses are distributed within a soil mass.
• Specify, conduct, and interpret soil tests to characterize soils.
• Understand the stress–strain behavior of soils.
• Understand popular failure criteria for soils and their limitations.
• Determine soil strength and deformation parameters from soil tests, for example, Young’s modulus,
friction angle, and undrained shear strength.
• Discriminate between “drained” and “undrained” conditions.
• Understand the effects of seepage on the stability of structures.
• Estimate the bearing capacity and settlement of structures founded on soils.
• Analyze and design simple foundations.
• Determine the stability of earth structures, for example, retaining walls and slopes.
