摘要
金属矿山千米竖井工程造价控制结构多设定为单层级,控制效率较低,导致最终工程造价价差增加。根据实际控制需求及标准,设定等效造价控制目标,采用多阶控制形式,提升整体的造价控制效率,完成造价控制结构的构建,建立基于LS-SVM的金属矿山千米竖井工程造价控制模型,采用竖井工程动态化监测及LS-SVM修正实现造价控制。测试结果表明:经过5次测定,与传统模糊自适应BP工程造价控制组、传统BIM工程造价控制组相比,LS-SVM工程造价控制组最终得出的可控价差控制在3万元以内,说明该造价控制方法的针对性与稳定性较高,控制效果更佳,具有实际的应用价值。
The cost control structure of metal mine vertical shaft engineering is often set as a single layer,which leads to low control efficiency and an increase in the final cost difference.Based on actual control needs and standards,an equivalent cost control target is set,and a multi-stage control form is adopted to improve the overall cost control efficiency.The cost control structure is completed,and a metal mine thousand-meter-level vertical shaft engineering cost control model based on LS-SVM is established.The cost control is achieved through the dynamic monitoring of the vertical shaft engineering and LS-SVM correction.Test results show that after 5 measurements,compared with the traditional fuzzy adaptive BP engineering cost control group and the traditional BIM engineering cost control group,the LS-SVM engineering cost control group finally controls the controllable cost difference within 30000 yuan.This indicates that the targeted and stable cost control method has better control effects and practical value.
