| 摘 要： | 以竖向集中荷载作用下Boussinesq位移解为基础，建立了地基沉降的可靠度分析模型，该模型完全可以取代基于单向压缩层的地基沉降分层总和法的概率模型。结合实例对荷载、沉降经验修正系数、土层压缩模量及土层厚度等参数的变异性对地基沉降可靠度指标的影响进行了较为全面的分析。 |
| 关 键 词： | Boussinesq位移解 地基沉降 概率分析 可靠度指标 |

| Abstract: | A model for the reliability analysis on foundation settlement based on Boussinesq's solution under the vertical con-centrated load is established herein; with which the probabilistic model based on the layerwise summation method for the foun-dation settlement of the uniaxial compression layer can be fully replaced. Furthermore, a comprehensive analysis on the effects from the variabilities of the parameters of both the empirical correction coefficient for the load and the settlement and the compressibility modulus of the soil layer on the reliability index of the foundation settlement is made as well. |
| Keywords: | Boussinesq's solution foundation settlement probabilistic analysis reliability index |
