| 摘要: |
| 绞吸挖泥船是水利工程疏浚施工领域广泛使用的一类工程船舶，安装在船上的工况监测系统能够实时记录船体的疏浚作业状态，但是所获得的实时监测数据并不能直接提供船体疏浚作业平稳度的关键信息。提出一种基于施工循环的绞吸挖泥船疏浚作业平稳度分析评价方法，通过选择合适的施工监测参数作为绞吸挖泥船疏浚作业平稳度分析指标，然后在预定义的施工循环内对平稳度指标进行计算分析，得到挖泥船在整个施工期间的疏浚作业平稳度变化情况，以及每个施工循环内的疏浚作业平稳度值。据所得的疏浚作业平稳度，能够判断挖泥船操作人员的疏浚作业平稳度优劣，并直观评价其相应的疏浚产量，为绞吸挖泥船的疏浚作业提供有效指导。同时，通过与传统的疏浚作业平稳度分析方法进行比较可见，所提出的方法能够定量地反映绞吸挖泥船在整个施工期间和每个施工循环中的平稳度变化情况，弥补了传统方法的不足，具有更强的实用性和优越性。 |

| Abstract: |
| The cutter suction dredger is a kind of construction equipment which is widely used in dredging construction in the field of hydraulic engineering. The states of dredging operations can be measured by a work condition monitoring system embedded into the dredger in real time. However, the obtained data cannot provide enough key information directly for the dredging operation smoothness. This paper presents a method to analyze and evaluate the dredging operation smoothness based on the construction cycles. At first, the appropriate monitoring parameters are selected as the index of the dredging operation smoothness. And then the dredging operation smoothness is analyzed in the predefined construction cycles, and the dredging operation smoothness values are obtained for both the whole dredging construction process and each construction cycle. According to the obtained results, the dredging operation smoothness of the operators and the corresponding dredging production can be evaluated intuitively, which provides an effective guidance for dredging operations. Meanwhile, compared with the traditional method for analyzing the smoothness of the dredging operations, the proposed method can reflect the changes in the smoothness values quantitatively for both the whole construction process and each construction cycle. In addition, the method given by this paper can make up for the shortcomings of the traditional method and has stronger practicability and superiority. |
