| Abstract: | This paper first introduced the application of similarity theory in the indoor model experiment, determined the related parameters of the model test. And then through the load model test of CFG pile composite foundation, this paper analyzed the relation of the natural foundation, composite foundation with no pile cap, composite foundation settlement with pile cap and pile soil stress. The conclusion can be made that CFG pile can effectively reinforce the loess foundation. |
