摘　　要：本文较全面地介绍了地基沉降的概率分析方法和可靠度计算方法 ,其中 ,较系统地介绍了随机有限元法在地基沉降概率分析和可靠度计算中的应用情况 ,并对随机有限元沉降分析中的随机场问题进行了评述 ,最后指出了地基沉降概率分析和可靠度计算的发展前景和发展方向。In this paper, the probabilistic methods of foundation settlement analysis and reliability assessment for the settlement problem are systematically reviewed, in which the stochastic finite element method used in the probabilistic settlement is emphasized. Moreover, the random field properties of soil profile inherited in the soil settlement problem is also studied. The future development and possible improvement are briefly discussed.
