Description

An introductory yet thorough discussion of all factors of driving a tunnel. Structured to take the reader from an introduction through comprehensive analyses of geotechnical considerations. Written so that a non-technically trained person will be able to understand the effects of geotechnical conditions on tunneling and make informed decisions regarding the best tunneling method for a particular situation (drill and blast, Tunnel Boring Machine, New Austrian Tunneling Method, roadheader, Earth Pressure Balance and soft ground tunneling.) The book aims to be readable, even to the non-engineer, without resorting to complex equations. About the Author Gary B. Hemphill has more than 30 years of experience in the construction industry TABLE OF CONTENTS Preface Acknowledgments 1 Introduction 2 Geotechnical Considerations--Rock Site Investigation Borings Obtaining Samples and Testing of Rock Geophysics Types of Rock Igneous Rocks Sedimentary Rocks Metamorphic Rocks Discontinuities Folds Fractures Faults Joints Shear Zones Hardness Tunnel Orientation Tunneling Under the Water Table Rock Mass Classification References 3 Soft Ground (Soil) Engineering Properties Squeezing Ground Swelling Ground References 4 Soft Ground Tunneling Unitary Excavation Full-Arch Mining Shields Slurry Machines Earth Pressure Balance Machine References 5 Tunneling In Rock Factors Considered When Selecting Tunneling Method Tunneling in Rock by Drilling and Blasting Drilling Explosives Blasting Tunnel Driving by Blasting Hydraulic Impact Hammer References 6 Road headers Operating Principle Mucking Machine Parameters Cutting Bits Operational Parameters Road header Cutting Capacity Performance Prediction Advantages of Road header Road header Shortcomings References 7 Tunnel-Boring Machines History of Tunnel-Boring Machine Channel Tunnel Beaumont / English Machine Operating Principle Cutting Tools Kerf Principle Disc Cutter Spacing Backup Equipment References 8 Ground Control Support System Objectives Types of Rock Support Active Support Passive Support References 9 Mucking and Haulage Mucking Methods Load--Haul--Dump Machines Mine Trucks Continuous Mucking Machine Rail Transport References 10 Grout Objectives of Grouting Geotechnical Grouting Materials Chemical Grout Grouting Pressures Stage Grouting Backfilling Contact Grouting Grouting Equipment Operating Tips References 11 Portals and Shafts Portals Shafts Locating Shafts Shape of Shafts Construction Collar Wood Sheet Piles Steel Sheet Piles Soldier Piles and Lagging Ribs and Lagging Liner Plate Slurry Walls Secant Piles Ground Freezing Drilling and Blasting Rock Shaft Mucking and Sinking Raise Borer Boxhole Borer Raise Climber Other Mechanical Methods Reference 12 Sprayed Concrete (Shotcrete) Dry Mix Wet Mix Additives Reinforcement Steel Fibers Synthetic Fibers Welded Wire Fabric Reinforcing Bar Application References 13 New Austrian Tunneling Method and Norwegian Method of Tunneling References 14 Water Handling Panning Pumping Dewatering Deep Wells Wellpoint Compressed Air Ground Freezing Reference 15 Trenchless Excavation Ramming Auger Boring Horizontal Directional Drilling Pipe jacking and Micro tunneling Drive Lengths Types of Excavators Box Jacking Reference 16 Tunnel Ventilation Introduction Fundamentals of Air Flow Fan Characteristic Curves References 17 Tunnel Lining Shotcrete One- and Two-Pass Lining Concrete Segments Cast-in-Place Concrete References Bibliography Index
