本文在对水下管道开沟机械的需求市场、实际应用和研制开发动向作深入调研的基础上，选择水下管道开沟机械特有的技术先进性、适用性、安全可靠性以及经济性评价指标，构造评价模型，对水下管道施工作业中广为应用的水力冲射开沟机械、海底管道犁、机械开沟机和土壤液化法埋管设备及其机型的技术经济性能作了较为详尽地分析对比及综合评价。在此基础上，笔者提出了水下管道开沟机械的一般选型原则和对我国海底管道开沟机械研究开发工

Technical and Economical Evaluation of Submarine Trenching Mechanics and It's Selection Criteria

It is most effective and economic way for solving the pipeline protection and stability to trench and bury pipelines below the seafloor. The author have made an investigation on require- ments of market, trends of application and development for submarine treching mechanics (STMs). The advantage suitability safety and economy of STMs is analyzed The evaluating mod- el is set up in the paper. Technical and economical performance of hydraulic jet trenching mechan- ics plough, mechanical cutting trencher and fluidization equipment are analyzed and comprehen- sivly evaluated in detail. On the basis of evaluation,the general criteria for the selection of STMs is presented by authors. Then some suggestions on selecting and developing STMs in our country are introduced.
