【摘要】 蜂巢挡土墙是一种生态自适应砌块挡土墙。由于蜂窝挡土墙具有土工格室力学性能好、施工方便、造价低等优点,在城市河道工程中得到越来越广泛的应用。本文基于砌块生态挡土墙整体结构安全要求,采用3个结构参数作为优化变量,对实际施工中的某河道工程项目进行结构局部优化搜索,得到蜂窝砌块挡土墙的综合最优结构形式。将多参数优化问题简化为分离变量优化方法,可在满足工程需要的条件下获得工程使用所认可的局部最优解。实际工程应用表明,通过这种简化搜索算法获得的结构形式是一种可行、经济的方法。更多还原

【Abstract】 The honeycomb retaining wall is a kind of ecological self-adapting block retaining wall. Because the honeycomb retaining wall has the advantages of good geocell mechanical properties, convenient construction and low cost, it is more and more widely used in urban river engineering. Based on the overall structural safety requirements of the block ecological retaining wall, this paper uses three structural parameters as optimization variables for a local optimization search for a river engineering project in practical construction, and obtains the comprehensive optimal structural form of the honeycomb block retaining wall. Simplifying the multi-parameter optimization problem into the method of separating variable optimization can obtain the local optimal solution recognized by the project under the condition of meeting the engineering needs. The practical engineering application shows that the optimized structure form through this simplified search is a feasible and economical method.更多还原
