Underground structures is abundantly illustrated to help students understand the material. Several examples are presented in related chapters. Problems are provided at the end of each chapter for homework assignment, and they are all SI units.     The authors have obviously devoted considerable effort to chapter preparation and they thank the various colleagues, publishers, websites and institutions who gave us permission to use and reproduce their copyrighted materials. Texts, tables and figures taken in whole or in part from various sources are acknowledged where they occur in the text.
