Abstract: Red clay is a widely distributed soil in Southern China. With the economic development in recent years, the demand for the bearing capacities for buildings with increasing height exceeds the capacity limit of the natural red clays. This paper presents a method that improving the bearing capacity of the red clay soil by using cement mixing. The design and construction aspects of the soil mixing in red clay are also introduced. The quality control measures during the construction are also proposed.

Key words: Red Clay, Bearing Capacity, Deep Mixing Method, Construction Techniques
