摘要
综合考虑影响边坡稳定性的各方面因素,用边坡的实测数据对网络进行了训练,建立了确定边坡稳定的遗传规划模型,用测试样本对模型进行测试,并应用于工程实例中。研究结果表明:运行结果通过二叉树的形式表达出来,更为直观,定性地确定了边坡稳定的主要影响因素与其安全系数的非线性关系;预测值与实测值是一致的,误差仅为3.48%,在工程允许范围之内,模型的预测性能是令人满意的。
In consideration of influencing factors of the slope stability,GP program was trained using practical data of the slopes,and then the slope stability model of GP was set up,finally the GP model was tested by the test samples and was applied to the engineering.The results show that the expression through the binary tree form is more intuitive,and determines qualitatively the nonlinear relationship between the main factors influencing slope stability and safety factor.The predicting result is in agreement with the measurement with errors of only 3.48%,and in the permission range of engineering,the predicting performance is satisfying.
