All such standards are developed by a cons

13、ensus standards process managed by the Societys Codes and Standards Committee (CSC). The consensus process includes balloting by a balanced standards committee made up of Society members and nonmembers, balloting by the membership of the Society as a whole, and balloting by the public. All standards

14、 are updated or reaf rmed by the same process at intervals not exceeding ve years. The following standards have been issued: ANSI/ASCE 1-82 N-725 Guideline for Design and Analysis of Nuclear Safety Related Earth Structures ASCE/EWRI 2-06 Measurement of Oxygen Transfer in Clean Water ANSI/ASCE 3-91 S

24、PMfmatter.indd viii fmatter.indd viii 5/3/2010 2:10:55 PM 5/3/2010 2:10:55 PMix SCOPE OF THE CONSENSUS GUIDE Compaction grouting is a ground improvement tech- nique that improves the strength and/or stiffness of the ground by slow and controlled injection of a low- mobility grout. The soil is displa

25、ced and compacted as the grout mass expands. Provided the injection process progresses in a controlled fashion, the grout material remains as a growing mass within the ground and does not permeate or fracture the soil. This behavior enables consistent densi cation around the expanding grout mass, re

26、sulting in stiff inclusions of grout surrounded by soil of increased density. This guide focuses speci cally on applications of compaction grouting where the increased strength and/or stiffness of the soil due to compaction is a primary element of the ground improvement. Applica- tions where a groun

27、d improvement design requires the injected grout to obtain a strength greater than that of the surrounding soil, although potentially a valid application of low-mobility grout, are not considered to be compaction grouting for the purposes of this guide and hence are beyond the scope of this document

28、. Both practical and theoretical aspects of compac- tion grouting are discussed. This guide follows the guidelines of the ASCE and uses the International System of Units (SI) as the primary system of units; imperial units are also provided in parentheses. Compaction grouting in North America typical

29、ly uses imperial units in the eld; hence many of the SI units have been calculated from the original imperial equivalents. In these cases an effort has been made to keep the “rule of thumb” values in their original form, and some loss of accuracy in the conversion between units may occur. This stand

30、ard may involve hazardous materials, operations, and equipment. This standard does not purport to address the safety problems associated with its application. It is the responsibility of whoever uses this standard to establish appropriate safety and health practices and to determine the applicabilit

31、y of regulatory and nonregulatory limitations. fmatter.indd ix fmatter.indd ix 5/3/2010 2:10:55 PM 5/3/2010 2:10:55 PMfmatter.indd x fmatter.indd x 5/3/2010 2:10:55 PM 5/3/2010 2:10:55 PMxi CONTENTS Standards . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
