Lateral Support Systems and Underpinning. Volume II. Design Fundamentals.

摘要

This report provides current information and design guidelines on cut-and-cover tunneling for practicing engineers. The main emphasis is on the geotechnical aspects of engineering. Included in this volume is a state-of-the-art summary of displacements and lateral pressure. Other topics are basic concepts of soil mechanics,ground water in open cut,passive resistance,design aspects of lateral earth pressure,stability analysis of sheeted excavations,bearing capacity of deep foundations,and construction monitoring. Detailed explanations of design methods and literature citations are included. Other reports prepared as part of the study are FHWA-RD-75-128,Volume I,Design and Construction;FHWA-RD-75-130,Volume 3,Construction Methods;and FHWA-RD-75-131,Concepts for Improved Lateral Support Systems.
