摘要
基于可靠度指标的几何涵义 ,运用遗传算法原理 ,提出了计算岩土工程可靠指标和设计验算点的全局优化算法。该方法模拟了生物遗传进化的过程 ,克服了传统方法容易陷入局部最小值的缺点。对于功能函数的非线性和复杂性 ,避免了有时甚繁的求导数工作。
Based on the geometric implication of the reliability index and genetic algorithm, a globe optimal algorithm is put forward to calculate the reliability index and the text point. It simulates genetic evolutionary process of organisms and avoids local minimum value. By this method, reliability of the nonlinear and complex performance function of geotechnical engineering can be got without derivation. Engineering examples show that this method is reliable and accurate.
