近来,在土工设计方面有建议采用极限状态设计方法。《加拿大基础工程手册》(1985)详述了这种新方法在基础,边坡、挡土结构物设计。一些新近的研究指出:使用极限状态设计与惯用方法设计,两者相比,前者显得保守。本文中介绍了参数研究的成果。调查、研究板桩墙的几何形状,考虑水压力的分布情况及不同的分析方法对锚板桩墙贯入深度的影响。修改常规的设计方法以使新的设计方法并与之相协调。
Recently, limit state design methods have been proposed for geotechnical design. The Canadian Basic Engineering Handbook (1985) details this new approach to foundation, slope, and retaining structure design. Some recent studies have pointed out that the use of limit state design and conventional method design, the former appear conservative. This article describes the results of the parametric study. Investigate and study the geometrical shape of the sheet pile wall, consider the distribution of water pressure and the different analysis methods on the influence of the penetration depth of the anchor sheet pile wall. Modify conventional design methods to harmonize new design methods.
