Preface This is the third Geotechnical Special Publication of the proceedings of Grouting 2017, the Fifth International Conference on Grouting, Deep Mixing, and Diaphragm Walls held in Hono
10、lulu Hawaii, U.S.A. July 9-12, 2017. Grouting 2017 is the fifth in a series of international conferences that began in 1982 to advance the science and technology of grouting, and these proceedings represent a five-year update from the previous conference in 2012 New Orleans. The three GSPs of these
11、proceedings capture 1) advances in the technology of materials, instrumentation, control, and the basic science of grouting, deep mixing and diaphragm walls that will lead to new and deeper understanding, new applications, and directions for the future; 2) exciting new information on Grouting and De
12、ep Mixing practices for monitoring and instrumentation technology that is becoming the new normal for these technologies throughout the world; and 3) new integration of multiple technologies for diaphragm wall construction and remediation. GSP 289 concentrates on Jet Grouting, Deep Mixing Methods, a
13、nd Diaphragm Walls with papers focusing on control, verification, and/or innovation. Very interesting case histories on dam cut-offs, excavation support, general soil improvement, and tunneling are included in this volume, highlighting the constant research being carried out in the grouting industry
14、, including innovation and varying approaches for production and verification. These proceedings have been produced thanks to international support of numerous organizations and individuals, including the: ASCE, Geo-Institute of ASCE, US DOT FHWA, Deep Foundations Institute, and International Confer
15、ence Organization for Grouting (ICOG). This publication culminates two years of effort by the planning committee whose focus has been to continue the vision established in the initial conference chaired by Wallace Hayward Baker and to keep the proceedings of this conference as the definitive source
16、of information on the cutting edge of grouting and related technologies. Many individuals are responsible for the content of this volume, all of whom served in the efforts to maintain the standard set by previous proceedings. Papers were reviewed in accordance with ASCE GSP standards. Accordingly, e
17、ach paper was subjected to technical review by two or more independent peer reviewers. Publication requires concurrence by at least two peer reviewers. The previous four conferences held in 1982, 1992, 2003, and 2012 were organized by the Grouting Committee of the ASCE/Geo-Institute and ICOG. ICOG i
18、s an independent organization that arose from the Grouting Committee of the Geo-Institute with the purpose of promoting the continuing growth of the understanding and use of geotechnical grouting. ICOG has worked closely with the Geo-Institute in the organization of this conference and preparation o

E-mail: hisho-stfit-chiba.ac.jp Abstract The multifan jet grouting method of ground improvement was developed to reduce the amount of redundantly improved soil. In this study, we geometrically examined the effectiveness of multifan-s
33、haped columns for lattice- or wall-form ground improvements. Consequently, ground improvement work could be performed more effectively with multifan columns than with oval or round columns. Furthermore, we developed new equipment to construct multifan columns, and conducted field tests to confirm it
34、s workability. Consequently, we confirmed our assumption that it is possible to construct multifan -shaped columns for ground improvement. INTRODUCTION Jet grouting is a technique for ground improvement which employs high pressure cement slurry and high pressure air (e.g. Shinsaka Uchida et al., 201
35、4). Until now, lattice- and wall-form improvements were constructed with round columns generated by jet grouting. Because the columns were round, more soil was improved than what was actually required, and more cement slurry was used than what was required. Furthermore, the cost of industrial waste
36、disposal was high. *URXWLQJ*63 $6 Awis the effective cross sectional area of the wall. From Fig. 8, it is clear that the MultiFan and oval columns demonstrated smaller values of redundantly improved soil body than that of round columns. Furthermore, the MultiFan columns had a smaller value of redund
37、antly improved soil body than that of oval columns. In other words, we identified the point at which unnecessary construction for the wall body becomes small. 0.81.01.21.41.61.80.0 0.2 0.4 0.6 0.8 1.0Column number rationCoefficient of wall thickness CwtRoundOval (Csd=0.8)Oval (Csd=0.6)Oval (Csd=0.4)

And so are the potential applications, although with the advantages that the elliptical geometry can bring into play and that will be described in the following paragraphs. MAIN BENEFITS As described above, the main reasons why the elliptical jet grou
46、ting technology was originally developed reside in the necessity of finding alternative, viable solutions to improve the efficiency of the traditional systems for the construction of diaphragm walls. In fact, the major benefits of this innovative technology are associated with the reduced column ove
47、rlaps needed to provide the same, for instance, wall width. As a matter of example, a continuous wall width is considered for the representations of Figure 3 where option a) shows the wall constructed by overlapping elliptical JG columns; option b) shows the same wall constructed with Cylindrical JG
48、 columns having the equivalent square footage of the elliptical columns; and option c) shows the same footprint constructed with cylindrical JG columns having the diameter equal to the major axis of the ellipses of option a). Figure 3: JG layout options to construct a diaphragm wall Although installation times (function of the injection parameters) and equipment capabilities, as well as design criteria and site specific conditions, may certainly vary, what appears evident in the sketch above is the much greater productivity and efficiency of the ell
