Abstract: In the soft ground treatment process of Xiamen Haicang Road, flat dilatometer test (DMT) is applied to get mechanical property of soft soil. From the DMT data and the comparison with several other in-situ tests, a conclusion can be drawn that DMT is simply to operate, can make less disturbance of soil and get many mechanical parameters exactly. The DMT for a soft ground treated with two different methods shows that the preloaded sand drain can obviously improve mechanical capacity of soft soil; the treatment effect will reduce while depth increase; and the cement injection pile has very little influence of the mechanical property of soft soil from a comparative long time.

Key words: DMT, soft ground treatment, CPT, CPTU, VST
