摘　　要：基于库伦被动土压力理论,考虑了土壤黏聚力、土壤与锚爪之间的黏着力以及土与锚之间的摩擦力,建立了可用于编程试算的制式锚锚定力计算公式;实例分析表明:与使用传统方法中的经验公式所得结果相比,更加精确;公式计算简单快捷,精度可靠,易于工程推广。Considering the cohesion force of soil, the adhesive force between soil and anchor and friction between the soil and anchor, a formula of standard anchor＇ anchorage force which can be applied to the trim calculation by programming procedures was proposed based on the coulomb passive earth pressure theory. Compared with the solution of the experience formula of traditional method it is more accurate. The present formula is convenient, reliable and easily to be applied in projects.
