شفت‌های حفاری شده در سنگ: تحلیل و طراحی

Drilled shafts in rock are widely used as foundations of heavy structures such as highway bridges and tall buildings. Although much has been learned about the analysis and design of drilled shafts in rock, all the major findings are published in the form of reports and articles in technical journals and conference proceedings. This book is the first to present and summarize the latest information in one volume, highlighting for the reader the principle differences between foundations in soil, and foundations in rock masses containing discontinuities. This book presents methods for characterizing discontinuities in jointed rock masses, and considering their effects on the behaviour of drilled shafts. A valuable tool for practitioners in geological engineering, rock mechanics and foundation engineering.
