| Abstract: | Jet powder pile is an economical, fast and effective method used in engineering to deal with soft ground. Combined with the construction of pile foundation in NanJing 4th bridge, the static loading test is done and the numerical evaluation calculation on the single dry-cement jet powder pile composite foundation is made by means of the three dimensional finite elements method （FEM）, a good agreement has been found between the results of finite element calculation and measured data. |
