Lateral Support Systems and Underpinning. Volume III. Construction Methods.

摘要

This provides specific design recommendations,design considerations,and construction techniques for the construction of lateral support systems and underpinning. The design considerations are presented for each technique or method (soldier piles,steel sheeting,diaphragm walls,internal bracing, tiebacks, underpinning,grouting,and freezing). The factors affecting the design or implementation of these schemes are discussed. Construction techniques are presented,and literature references are provided for those seeking even greater detail. An overview of the construction methods compares the applicability of the techniques and the construction costs of each. Other reports developed from the study are FHWA-RD-128,Volume I,Design and Construction;FHWA-RD-129,Volume 2,Design Fundamentals;and FHWA-RD-131,Concepts for Improved Lateral Support Systems.
