Case histories of ground improvement solutions using jet-grouting ABSTRACT The aim of this paper is to present the main design and construction criteria considered on some vertical jet-grouting solutions adopted by Tecnasol FGE. On these solutions ground improvement by vertical columns was successfully used as an alternative to traditional solutions, such as concrete cast in-situ pile foundations, earth retaining sheet pile walls and micro-piles for underpinning. On each case history, the following topics are presented: main scenario, geotechnical conditions, initial solution, main design criteria and construction issues. منبع @civilbest Improvemen Jet grout.pdf

Improved performance of soft clay foundations using stone columns and geocell-sand mattress Sujit Kumar Dash a, *, Mukul Chandra Bora b a Department of Civil Engineering, Indian Institute of Technology Kharagpur, Kharagpur 721 302, India b Department of Civil Engineering, Indian Institute of Technology Guwahati, Guwahati 781 039, India a r t i c l e i n f o Article history: Received 23 November 2012 Received in revised form 23 August 2013 Accepted 31 August 2013 Available online 21 September 2013 Keywords: Foundation Geosynthetics Stone columns Ground improvement a b s t r a c t A series of experiments have been carried out to develop an understanding of the performance improvement of soft clay foundation beds using stone column-geocell sand mattress as reinforcement. It is found that with the provision of stone columns, of adequate length and spacing, about three fold increases in bearing capacity can be achieved. While with geocell-sand mattress it is about seven times that of the unreinforced clay. But if combined together, the stone column-geocell mattress composite reinforcement, can improve the bearing capacity of soft clay bed as high as by ten fold. The optimum length and spacing of stone columns giving maximum performance improvement are, respectively, 5 times and 2.5 times of their diameter. The critical height of geocell mattress can be taken equal to the diameter of the footing, beyond which, further increase in bearing capacity of the composite foundation bed is marginal. بهبود عملکرد ستونهای سنگی با یک لایه ژیوسل در بخش فوقانی منبع Dash & Bora 2013.pdf
