...Itsuki Sato; Hidenori Takahashi Representative methods for deep mixing in cement stabilisation treatment of grounds include mechanical mixing, jet grouting, and trencher mixing. These methods differ not only in their stabilisation mechanisms but have also evolved independently, and are seldom...

...A. Flora; G. P. Lignola; G. Manfredi A possible approach is shown for the design of jet grouted umbrellas, which are often used as temporary supports in tunnelling practice. In the current paper it is argued that such an approach should be probabilistic or semi-probabilistic. Based on published...

...P. Croce; G. Modoni This paper deals with the design of jet-grouting cut-offs for dams. Available information from several cases is first reviewed, pointing out the differences between projects concerning dams under construction and operational ones. Various dam types and treatment schemes...

The paper presents details of the execution...

...Y. S. Fang; C. C. Kao; J. Chou; K. F. Chain; D. R. Wang; C. T. Lin This paper introduces the superjet-midi (SJM) method, which has been developed to improve the efficiency of jet grouting. The diameters of soilcrete columns constructed with the new method are relatively large (2·4–3·5 m...

...J. Morey; D. W. Campo This paper presents a review of the jet grouting works of Line 2 of the Greater Cairo metro system. During the project over 80 000 m³ of ground was treated using the jet grouting method, making this one of the largest jet grouting endeavours worldwide to date...

...J. P. Welsh Grouting techniques in North America are generally categorized as follows: slurry grouting, permeation grouting, compaction grouting, jet grouting and soil fracture grouting. In addition to reporting on the state of the art of grouting, this paper traces the history of each...

..., element walls, micropiles and stone columns. The chemical treatment methods discussed are those applied at depth such as permeation grouting, jet grouting, deep soil mixing and lime columns. Thermal stabilization is covered through ground freezing and its use in urban construction. Finally, biotechnical...
