Abstract: The dynamic replacement technique as the deep excavation support is a new soil engineering technology. The basic principles, construction sequence as well as the technical control standards of this technology are discussed in this paper. In addition, the successful application of this method in a deep excavation support of a nuclear power plant is also presented. It is found that the results are effective and satisfactory. The results in this paper can provide references for similar projects.
