工程地质类比法程序化设计

The Programmed Design of Engineering Geological Analogy Method

工程地质类比法作为一种经验迁移法,在应用过程中,人的主观意识起很大作用,故将人工神经网络与遗传算法相结合,智能化地建立不同工程之间非线性映射关系,将工程地质类比法程序化,降低了人为因素造成的差异性和不确定性,并通过边坡工程实例验证了该方法的可行性.

Engineering geological analogy method is often considered as an experience method, which provides physical-mechanics parameters of rock and soil in the project design and construction. However, it is found that the different engineers obtain different results in the process of its application. A programmed design of engineering geological analogy method is introduced based on a combined arithmetic between BP neural network and Genetic Algorithm,which can automatically establish a high-nonlinear mapping relation between different projects and reduce the diversity as well as the uncertainty. The feasibility of this new method is proved by slope engineering case study.
