DAM FOUNDATION GROUNTING
Kenneth D.Weaver. Donald A. Bruce Ph.D.
This book provides a state-of-the-practice review of all aspects of drilling and grouting-based technologies used for dam foundation treatment. Like its first edition, the book provides readers with background information and guidance to understand and deal more confidently with issues related to the design, construction, supervision, analysis, and review of grouting programs.
The new edition of Dam Foundation Grouting has been revised to reflect contemporary grouting practice and has been substantially enlarged to include coverage of geologic considerations and to address remedial grouting issues. In addition to providing extensive information on grouting technology, equipment, and procedures, it also provides guidance of specifications and contracts.
Dam engineers, dam construction engineers, grouting supervisors and inspectors, field personnel of dam safety reviewing agencies, and engineering students will benefit from this book.
