| Abstract: | The mechanism for reinforcing soft earth foundation by jetting concrete powder then stirring it is briefly introduced. The calculation method is discussed on reinforcing the foundation by powder-injected pile from a practice of treatment with the Hu-Rong Expressway (at Hu-Ning segment) . This kind of pile can accelerate earth-filling rate of road dyke and effectively control post-work subsidence, ensuring the construction quality. |
