By use of the indoor model test method，the tests have been carried on between the composite foundation of pipe-pile with cap and holes，which are three kinds of arrangement holes，and the composite foundation of pipe-pile with cap and without hole，the character rules of soil pressure between two pile caps，soil pressure under pile cap，pile-soil load sharing ratio and pile-soil stress ratio of the composite foundation of all piles have been analyzed comparatively. The test results show that the soil pressure between two pile cap of the pipe-pile with holes is greater than that of pipe-pile without hole，the pile-soil load sharing ratio and the pile-soil stress ratio of the composite foundation of pipe-pile with cap and holes is smaller than that of composite foundation of pipe-pile with cap and without hole，the soil around pipe-pile can play the more role of the load sharing in the composite foundation of pipe-pile with cap and holes. These results can confirm that the pore water can go into the inner cavity of the pipe-pile with holes through the pile holes，reducing soil water content，improving the shear strength of soil. These results can also provide the test basis for theoretical study of composite foundation of pipe-pile with cap and holes，and the guidance for its application.
