This practical guide to advanced geotechnical topics helps readers solve problems in real–world situations.

Taking a personal tone and devised with a focus on practical aspects, Geotechnical Problem Solving bridges the gap between geotechnical and soil mechanics material covered in university Civil Engineering courses and the advanced topics required for practicing Civil, Structural and Geotechnical engineers. By giving newly qualified engineers the information needed to apply their extensive theoretical knowledge, and informing more established practitioners of the latest developments, this book helps readers confidently approach problems having thought through the various options available. Where various competing solutions are proposed, the author systematically guides readers through each option, weighing the benefits and drawbacks of each, to ensure they can approach and solve real–world problems in a similar manner.

  • Links theoretical and practical work to provide a reference and guide to geotechnical topics
  • Takes readers through various scenarios helping them to understand how to solve problems efficiently
  • Provides a perspective on complexity in geotechnical practice
  • Gives readers the tools they need to understand the principles and history behind the material so that they can handle real–world problems
  • Covers a broad range of geotechnical topics, including soils, foundations and retaining structures, and provides an introduction to the background and application of geotechnical LRFD
  • Reading recommendations are  given including special articles and  references for further study of advanced material
  • Uses a problem and answer mentoring approach from the author to the reader to answer many of the reader s questions

Dr John Lommler is a practicing geotechnical engineer with 44 years experience in teaching, consulting and mentoring in Structural and Geotechnical Engineering.  Dr Lommler is principal geotechnical engineer for AMEC in New Mexico and Texas.  He began his career in Ohio in 1967 as a student structural engineer working on power plant projects.  His career changed from structural to geotechnical engineering after studying under and mentoring received from Dr David Timmerman at the University of Akron.

Dr Lommler taught and practiced consulting geotechnical engineering in Ohio until 1991.  When he moved to New Mexico to help his wife s health, the move introduced him to arid, unsaturated, collapsible soils with Bob Booth and George Beckwith, which reinvigorated his career.  In Albuquerque, he connected with Dr Ralph Peck, who inspired, mentored and encouraged him to continue geotechnical consulting practice past retirement age, mentor younger engineers, and write his book, Geotechnical Problem Solving.               

Dr Lommler has written or co–authored over 1100 geotechnical reports and studies for commercial, municipal, state and federal government clients.  He is author and co–author of several reports on Uranium Mill Tailings disposal cell design available from federal publishing sources, and is co–author of several geotechnical papers published in conference proceedings available from ASCE and the Geo–Institute.
