ABSTRACT
ABSTRACT: The solution of lime and soil-cement pile appeared since the 1970s and widely used in Sweden and other countries in the Scandinavian, CDIT (2002), with many advantages such as stabilize soft soil, reduce settlement, increase the resistance work load, make use of local materials, reduce costs and less environmental pollution as well as increase the earthquake resistance of buildings. Nowadays, this technology has been developed in many countries like the USA, Japan, China, ... In Vietnam, the technology of soil-cement piles was known in 1980s and has had particular application in the construction of diaphragm wall, road, abutment, ... or some building low-rise residential Nguyen at al (2010). Da Nang city is located on the coastal strip of central Vietnam where the geological characteristic is mainly sandy with the sand grain size from medium to small. The condition of soil in this area is quite hard with the sand surface about (10 ÷ 15)m thick from the ground. Therefore, soil-cement pile is very good in application here with the compressive strength up to (5 ÷ 10)MPa. This method of construction not only reinforces the foundation but also is used to load pressure of high-rise buildings foundation. The article presents some case studies for building works that soil cement piles have been successfully used in Da Nang.
