Gregory Tsinker brings his extensive knowledge of structural engineering and geotechnical design to his translation of George E. Lazebnik's work on soil-structure interaction. Monitoring of Soil-Structure Interaction is aimed at professional geotechnical and foundation engineers who deal with soil-foundation interaction, soil pressure distribution, or ground monitoring instruments. This book will incorporate original data and emphasize practical, mathematical models for measuring soil pressure on the foundations of a structure. Readers will be able to compare their calibrated measurements to the data presented in the book.
