Experimental Study on T-Shaped Soil-Cement Deep Mixing Column Composite Foundation
Soil-cement deep mixing method is widely used in soft ground improvement for highway engineering application in China. However, there are some disadvantages of the conventional soil-cement deep mixing method in China, such as insufficient mixing, grouting spill and decrease of strength along column depth. In addition, small column spacing and cushion or geosynthestic reinforcement are often required, resulting in high cost. In order to conquer these disadvantages, a new deep mixing method named T-shaped deep mixing method is developed. The mechanism, construction issues, and pilot project monitoring results of T-shaped deep mixing column foundation are presented in the paper. The results indicate that the T-shaped deep mixing method makes the deep mixing much more reliable and economical.
