Two-Dimension Golden Section Method for Cross-Section Optimum Design for the Slide-Resistant Piles

Slide-resistant pile is one of the most important measures in the landslide improvement. However, recent studies are mainly concerned with the interval and anchoring length during the slide-resistant pile design and few discuss the section dimension of the pile. Therefore, based on the analysis of the relationship between cross section width and cross section height and total cost, the two-dimension golden section method and computer programming methods are introduced to solve the problem by the author. Special computing software is developed to complete the optimal design for slide-resistant pile cross-section. This optimizes the project cost and satisfies the safety requirement. The application to landslide resistance design in the Three Gorges Reservoir Area proves that this optimum method is quite economically effective, and thus applicable in the slide-resistant pile design.
