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:
