Abstract: Aiming at the blindness and controlling afterwards existing in the expressway soft ground design and construction, a method of dynamic simulation design was put forward to control the soft ground construction. According to the data achieved through soft ground monitoring, a simulation calculation was used to design the fill height and the filling rate of each construction stage, a loading project was done. Monitoring was going on through the process of construction. We analyzed the data achieved to amend geologic parameters used in the next step of simulation calculation. Carrying on this procedure time after time, dynamic simulation control and dynamic design of the whole process of construction is realized. The flow chart of the whole dynamic simulation design was established here. Problems of how to calculate some soil parameters such as consolidation coefficient by the monitoring data, and how to take the strength increase of the soft soil into account was solved in the dynamic simulation design too. Applying in the construction of an expressway, this method turned the construction from mode of controlling afterwards to the mode of controlling beforehand, avoided blindness and many accidents in the construction effectively.

Key words: soft ground, dynamic simulation design, controlling beforehand, strength increase
