| 摘 要： | 应用可靠度计算的改进JC 法, 以岩体Hoek2Brown 强度准则为例, 针对极限状态方程的高次非线性和复杂性,分别采用变量代换法、Monte2Carlo 法、复合函数求导法和引用有理多项式技术计算三维岩体强度准则的可靠指标β。结果表明, 岩土工程可靠度计算中引入有理多项式技术的方法优于其他方法, 而且便于编制通用的可靠度计算程序。

| Abstract: | Using the improved JC method in association with an example of Hoek Brown criterion, the variables replacing technique, the compound function method as well as the rational polynomial technique are adopted in the calculation of reliability index to consider the high order nonlinearity and the complexity of the performance function in geotechnical engineering. Moreover, Monte Carlo method is employed as comparison. The results show that the method of adopting the rational polynomial technique is better than the other techniques because it is easier in calculation and more convenient in developing computer program. |
