摘 要:在高拱坝混凝土浇筑中,多台缆机通常同时分条带浇筑多个浇筑仓,故缆机群对浇筑仓条带的浇筑协同优化是提高施工效率的关键。因仓面运距和条带面积的差异导致各缆机的浇筑效率不同,简单的等分仓面难以保证条带协同浇筑上升,进而影响缆机群的浇筑效率。针对上述问题,提出了一种兼顾浇筑循环时间和负载均衡的缆机群智能配置模型。首先,对各缆机覆盖范围与浇筑仓重叠的区域进行浇筑条带划分,将缆机群与浇筑仓的配置转化为缆机群与条带的组合优化问题。提出“微匹配”模型桥接缆机和多条带,将缆机和浇筑仓的多对多关系转换为缆机和微条带一对一匹配关系,并建立浇筑组合优化的“微匹配”积分表达。最后以循环时间、负载均衡为优化目标求取缆机群的优化配置方案,实现浇筑条带的协同上升。白鹤滩拱坝浇筑配置例表明:缆机的浇筑循环时间、吊运负载基本保持均衡,上层缆机浇筑强度平均值偏差为-6.8%,下层缆机浇筑强度平均值偏差为5.1%。方法对缆机和浇筑仓数量变化具有良好的适应性,具有一定的智能配置能力。In the concrete pouring of the high arch dam,multiple cable cranes usually pour multiple pouring blocks based on strips.So the key to improving construction efficiency is to optimize cable cranes to the coordination of pouring blocks strips.The difference of transportation distance and strip area leads to different pouring efficiency of each cable crane,and simple equal surface of the pouring block hardly guarantees the strip collaborative pouring rise,then the pouring efficiency of the cable crane group is affected.In order to solve the above problems,this paper establishes an intelligent configuration model of cable crane group,which takes into account the pouring cycle time and load balance.Firstly,the pouring strip is divided for the area where the coverage of each cable crane overlaps with the pouring block and the configuration of cable crane group and pouring blocks is transformed into a combination optimization problem of the cable crane group and the strips.Subsequently,a“micro-matching”model which bridges the cable machine and multiple strips is proposed.The many-to-many relationship between cable cranes and pouring blocks is transformed into a one-to-one matching relationship between the cable crane and the micro strip,and the“micro-matching”integral expression of the pouring configuration optimization is established.Finally,the optimal configuration scheme of the cable crane group is obtained with the optimization objectives of cycle time and load balancing,and the coordinated rise of pouring strips is realized.The pouring configuration example of Baihetan arch dam shows that the pouring cycle time and lifting load of the cable crane is basically balanced.The average deviation of the upper cable crane pouring strength is-6.8%,and the average deviation of the lower cable crane pouring strength is 5.1%.This method has good adaptability to the change of the number of cable crane and pouring block,and has certain intelligent configuration ability.
