摘　　要：低桩沉箱式平台受较大的波浪力和海冰冰力的作用,其桩的疲劳问题比较突出。本文分别用S—N曲线法和断裂力学法对桩的疲劳问题进行了分析,同时考虑了土壤软化的影响。The piled caisson platform is often subjected to the bigger forces from waves and sea ice, therefore, the fatigue of the piles is the notable problem. The paper analyses the fatigue of piles respectively by S - N curve and fracture mechanics, and considers the influence of soil softening sinuously.
