高压旋喷桩加固软土地基研究

High-pressure rotary jet pile is a new technique of reinforcing foundation which has a lot of advantages. With the construction of numerous foundation projects, the application of High-pressure rotary jet pile is more extensive. Based on the geological site conditions and existing norms, the paper designed reinforcement scheme. The archile carried out the test of the bearing capacity of the composite ground ,soil-cement strength of pile and vertical resis compression static test of single pile, the results showed that the design meets the requirements of reinforcement. Meanwhile the paper introduced the site management, operating gist and quality detection of High-pressure rotary jet pile.
