Abstract: Based on Longda expressway of Shenzhen-Longda ,this paper analyses and researches the treatment of our country shallow layers of soft soil ground. Besides, the text observes，compares，analyses and summarizes the disposal schemes according to the different topographical, different geological condition and different soft soil grounds, and finds an economical, suitable treatment scheme  which can reduce project fabrication cost greatly, and economize production cost. It has important directive significance on practice of similar large projects.
