摘要
伴随河道工程和港口建设的发展,疏浚工程对于保证抓斗平挖过程的稳定性、控制抓斗准确定位、保证挖掘精度也提出了更高的要求。通过总结水流、波浪和船倾这3大因素对抓斗水下平挖作业的综合影响,应用模糊数学理论改进的层次分析法对水流和船倾因素在位移上的影响程度进行评估。结合疏浚平挖过程的特点和实际作业工况,以保证平挖精度为目标,对3项因素对抓斗平挖过程的影响权重给出意见。
With the development of the river channel project and harbor construction , dredging works have higher re-quirements on the stability of the grab during digging process , accurate positioning of the grab , and digging precision.By analyzing the effect of the water flow , wave, and ship tilting on the underwater digging operation of the grab , the paper a-dopts the analytic hierarchy process improved from the Fuzzy Mathematic Theory to evaluate the effect of water flow and ship tilting on the displacement Considering the features of dredging and digging process and actual working conditions , the pa-per gives on the effect weight of the three factors to ensure the precision of grab digging .
