| 摘 要： | 利用BP神经网络模型和可靠度理论对我国大量液化和未液化场地标准贯入试验数据进行分析,得到了地震时饱和砂土液化极限状态函数和液化概率函数。本文建议以这两个函数为基础建立新的液化判别标准。 |
| 关 键 词： | 神经网络模型 液化极限状态函数 失效概率函数 液化判别标准 液化临界加速度 |

| Abstract: | A large database consisting of SPT test at liquefied and unliquefied sites in China is analyzed by ANN model and reliability theory. The liquefaction limit state function of saturated sandy soils during an earthquake and the probability function are given in the paper. Suggestion of establishing a new liquefaction criterion in China is presented based on these two functions. |
| Keywords: | artificial neural network (ANN) liquefaction limit state function liquefaction probability function liquefaction potential criterion critical acceleration of liquefaction |
