在分析水平荷载作用下桩的不排水荷载时，一个重要的量是桩身深度对纯水平运动的极限侧阻力。如果将土体模型化为理想塑性粘性材料，则这个量的计算归结为塑性理论中的平面应变问题，即荷载是在无限大介质中横向运动的长圆柱体上计算的。给出了这种圆柱体上载荷的精确计算。如果这种荷载是关于土体强度和桩直径的无量纲化的，则发现荷载系数在完全光滑的桩和完全粗糙的桩之间变化。这一结果是在以前的桩的横向承载能力计算的背景下讨论的，并与利用空洞扩张理论和土面附近的楔形破坏的近似计算进行了比较。La阻力的侧限在水平方向上代表着参数的变化。
In the analysis of the undrained loading of laterally loaded piles an important quantity is the ultimate lateral resistance at depth to purely horizontal movement. If the soil is modelled as a perfectly plastic cohesive material then the calculation of this quantity reduces to a plane strain problem in plasticity theory, in which the load is calculated on a long cylinder which moves laterally through an infinite medium. An exact calculation of the load on such a cylinder is presented. If this load is non-dimensionalized with respect to the soil strength and the diameter of the pile, it is found that the load factor varies between for a perfectly smooth pile and for a perfectly rough pile. This result is discussed in the context of previous calculations for the lateral load capacity of piles and is compared with approximate calculations using cavity expansion theory and a wedge failure near the soil surface. La resistance laterale limite en profondeur au seul mouvement horizontal represente un parametre im...
