This volume presents procedures and guidelines applicable to the design and instal tion of prefabricated vertical drains to accelerate consolidation of soils. The contents represent the Consultant's interpretation of the state-of-the-art as of August 1986. The volume is intended to provide assistance to engineers in determining the applicability of PV drains to a given project and in the design of PV drain systems. The information contained herein is intended for use by civil engineers familiar with the fundamentals of soil mechanics and the principles of precompression. The volume includes descriptions of types and physical characteristics of PV drains, discussion of design considerations, recommended design procedures, guideline specifications and comments pertaining to installation guidelines, construction control, and performance evaluation. This volume is the first in a series. The others in the series are: FHWA No. Vol. No. Title RD-861169 - II Prefabricated Vertical Drains: Summary of Research Effort RD-861170 III Prefabricated Vertical Drains: Laboratory Data Report RD-861171 I Geocomposite Drains: Engineering Assessment and Preliminary Guidelines RD-861172 II Geocomposite Drains: Laboratory Data Report
