基于经济效益的土工格室挡土墙优化设计研究

Optimization Design Research on Geocell Retaining Wall Based on Economic Benefits

为了节约土工格室技术在挡土墙中应用时的工程成本,建立了基于遗传算法的数学计算模型,提出了一种基于经济效益的工程优化设计的方法,给出了格室筋带长和挡墙高度的参考值,并应用于京港澳高速公路驻马店至信阳段的优化设计。结果表明:这种优化设计方法能有效节约工程材料,降低工程成本,具有可行性。

To save the project cost of applying geocell technique to retaining wall, the paper established mathematical calculation model on the basis of genetic algorithm, and proposed a method for enigneering optimization design on the basis of economic benefits,it gives the reference values of the geocell reinforcement length and the retaining wall height.then applied it to the optimization design of Zhumadian-Xinyang Section of G4 Beijing-Hong Kong-Macao Expressway. The result shows that this optimization design method may be useful to save the engineering material and reduce the project cost, thus it is feasible.
