    摘要: 本文利用土塊分析法分析擋土背後砂土 的主動土壓力係數,本法假設背後的土塊沿 由對數螺線及直線所組合的複合滑動面滑動, 並利用一扇形自由體進行力矩平衡之分析。本 文所得結果與其他較複雜方法相較時,以水平 地面及垂直背為例,其結果最接近Sokolovski的 主動土壓力係數。本文並列出一般常用到的土 壓力係數值。
    This paper computes the coefficients of active earth pressure on sand by the wedge method. When the soil is at active state, the sand behind the wall is assumed to slide along a composite failure surface which is composed of a logarithmic spiral and a line. A fan-shaped free body is utilized in the analysis. Results obtained from this paper is mostly close to the Sokolovski's data, when compared with other solutions, for level ground and vertical wall. The computed coefficients of active earth pressure for several cases are also included.
