Abstract
The foundation of 1~16t hammer have been calculated with five calculation models and compared with the test data of the foundation and anvil for the hammer 1t, 2t, 3t, 5t, 10t and 16t built on the loess clayey loam stratum. The results show: (1) In the design of hammer foundation, calculation with model of two-degree-freedom and damped agrees rather better with the actual measurement. (2) The coefficient of subgrade compression rigidity increases with the increase of the depth of soil stratum. Both accurate calculations of the coefficient of subgrade compression rigidity and effected depth under the hammer foundation are most significant for designing a rational hammer foundation. In this paper formulae are presented for calculating optimum ratios of anvil mass to hammer foundation mass and pad rigidity to subgrade rigidity according to different kinds of soil and different tonnages of the hammer.

Theory and Experiment of Hammer Foundation Vibration
The foundation of 1~16t hammer have been calculated with five calculation models and compared with the test data of the foundation and anvil for the hammer 1t, 2t, 3t, 5t, 10t and 16t built on the loess clayey loam stratum. The results show: (1) In the design of hammer foundation, calculation with model of two-degree-freedom and damped agrees rather better with the actual measurement. (2) The coefficient of subgrade compression rigidity increases with the increase of the depth of soil stratum. Both accurate calculations of the coefficient of subgrade compression rigidity and effected depth under the hammer foundation are most significant for designing a rational hammer foundation. In this paper formulae are presented for calculating optimum ratios of anvil mass to hammer foundation mass and pad rigidity to subgrade rigidity according to different kinds of soil and different tonnages of the hammer.
