Abstract：In order to quickly determine the ultimate bearing capacity of gravel pile reinforced soft soil strip foundation,this paper establishes an analysis model for the bearing capacity of gravel pile improved soft clay based on the Morgenstern Price slicing method.Based on this analysis model,parameter research was conducted and Gaussian and linear fitting were performed.The research results indicate that the established analysis model has achieved good results,and the best improvement effect can be achieved when the spacing/diameter ratio(S/D)is equal to 1.4.The improvement rate(IR)significantly increases with the increase of permutation rate,and the fitting results of parameters and improvement rate(IR)have high accuracy,which provides a scientific basis for the application of crushed stone pile reinforcement of soft soil strip foundation.
