悬臂挡土墙应用最为广泛,因为当挡土墙高度在3～6m范围内,与重力式或半重力式挡土墙相比,悬臂挡土墙较为经济。文章提出当挡土墙高度在3～6m范围内,钢筋混凝土悬臂挡土墙的优化问题,其优化的横断面如第31页图1(a)所示。 分析悬臂挡土墙时,作用于断面的各种力示于图1(a)。在优化问题中,预先选定的
Cantilever retaining wall is the most widely used, because when the retaining wall height in the range of 3 ~ 6m, compared with gravity or semi-gravity retaining wall, cantilever retaining wall is more economical. The paper proposes the optimization of RC cantilever retaining wall when the height of retaining wall is within 3 ~ 6m. The optimized cross section is shown in Fig. 1 (a) on page 31. When analyzing cantilever retaining walls, various forces acting on the cross-section are shown in Figure 1 (a). In the optimization problem, preselected
