当設計带有斜桩柱的桥墩台基础时,設計部門常釆用高桩承台的計算法。此方法的特点为土壤抵抗每桩位移的分布强度系用两个假定的刚性固定点来代替:一个阻止桩的垂直位移;另一个阻止水平位移与扭轉。这些固定点的第一个位置用以确定桩的受压計算长度L_N(图1);而第二个位置用以确定受挠长度L_M。 When designing a bridge pier foundation with diagonal piles, the design department often adopts the calculation method of high pile cap. The characteristic of this method is that the distribution of soil resistance per displacement is replaced by two assumed rigid anchors: one to prevent vertical displacement of the pile and the other to prevent horizontal displacement and torsion. The first position of these fixed points is used to determine the calculated compression length L_N of the pile (Figure 1), while the second position is used to determine the length of flexure L_M.
