The Numerical Analysis Of Pile-soil Interaction In H-type Sheet-pile Wall

The sheet-pile retaining wall is widely adopted in the landslides or slopes remedy. The pile's capability of resist-wrench are mainly up to pile's stiffness. However, it's finite only on the pile's section dimension. Furthermore, the large-section pile is costly and difficult to construct. So these years h-type sheet-pile wall is widely constructed. They have the same parameter, the smaller section, bigger stiffness of resist-wrench, less material, shorter embedment depth and resisting bigger slide press.Predecessor have greatly study on single pile and it is simple compare to h-type sheet-pile wall. In this paper, the main content is to apply numerical analytic method to research and analysis the interaction between slide-resistant piles and soil combined with a real example. According to numerical analysis, it's found that the vice-pile greatly sustains the main-pile by the link beam while it doesn't directly bear the slope slide-force, so the main-pile has more slide-resistant capability. In succession, the internal force of numerical method and that of the general analytic method are compared, and it's shown that the internal force of the analytic method partly deviates from the real face for these assumptions of slope press distribution, reaction distribution of soil between piles, and so on. Therefore, it's necessary to utilize several kinds of method or means, general analytic method and numerical method or experiment and monitoring to solve the geotechnical problems.
