带有斜拉锚桩的薄壁板桩墙,计算方面属于具有刚性横梁和弹性支柱的框架结构。作用于结构上的荷载有土压力和压在斜桩上的土重。下面介绍的是作者提出的适用于实际使用范围内任何锚桩斜度的计算方法。本计算方法系利用变位法计算原理。板桩墙在土中的嵌固点位置及其计算长度事先是不知道的。为了确定这两个数值以及为了进一步研究对结构体系变位的影响,框架的横梁用一任意的连杆1加以约束(图1a)。这样一来框架力系就变为具有
Thin-walled sheet pile walls with anchored anchors are computationally part of the frame structure with a rigid beam and flexible struts. Soil loads acting on the structure and bearing on the slant pile. Described below is the calculation method proposed by the authors for any anchor pile inclination within the actual range of use. The calculation method is the use of displacement method to calculate the principle. The location of the embedment point of the pile wall in the soil and its calculated length are not known in advance. In order to determine these two values and to further investigate the effect on the displacement of the structural system, the beam of the frame is constrained by an arbitrary link 1 (Figure 1a). As a result, the framing force becomes available
