本文采用复合形法对钢筋砼悬臂式挡土墙进行优化设计,除考虑了填土的作用外,还考虑了土体表面具有满布均布荷载、局部均布荷载以及集中线性荷载的各种情形。全部约束均按现行规范的要求列出,并取挡土墙的总造价为目标函数。在此基础上编制了微电子计算机程序GHDC-87,与传统的设计法相比,采用本设计法一般可降低造价10％左右。
In this paper, the complex method is used to optimize the design of the reinforced concrete cantilevered retaining wall. In addition to the consideration of the role of the filling, it also considers that the surface of the soil has all kinds of uniformly distributed loads, local uniform loads, and concentrated linear loads. situation. All constraints are listed in accordance with the requirements of the current specification, and the total cost of the retaining wall is taken as the objective function. On this basis, a microelectronics computer program GHDC-87 was compiled. Compared with the traditional design method, this design method can generally reduce the cost by about 10%.
