河道清淤方量测、算方法应用分析

Application Analysis of Measurement and Calculation Methods for Dredging in River Channels

疏浚河道,是生态环境治理、防洪排涝有效手段。清淤方量测、算数据是工程招投标、施工预决算的重要依据。河道清淤测、算方法多样,各具技术特点,作业效率和成本投入迥异。以杭州市某年河道清淤工程为例,列举不同的外业数据采集模式和内业数据处理方法,对比测、算结果,进行适用性和差异性分析。结果表明,根据河道周边环境和历史数据,选择适用的清淤方量测、算方法,能够及时提供可靠测绘成果,满足清淤工程规划设计和施工需要,助力城市河道综合整治。对河道清淤方量测、算方法进行分析研究,具有工程应用意义。

Dredging river channels is an effective means of ecological environment management and flood control and drainage.The measurement and calculation data of dredging are important basis for engineering bidding and construction budget and final settlement.There are various methods for measuring and calculating river dredging,each with its own technical characteristics,and the operational efficiency and cost investment vary greatly.Taking a certain year's river dredging project in Hangzhou as an example,different field data collection modes and internal data processing methods were listed,and the results of measurement and calculation were compared for applicability and difference analysis.The results indicated that selecting suitable dredging measurement and calculation methods based on the surrounding environment and historical data of the river could provide reliable surveying and mapping results in a timely manner,meet the planning,design,and construction needs of dredging engineering,and assisted in the comprehensive improvement of urban river channels.Analyzing and researching the measurement and calculation methods for dredging in river channels has engineering application significance.
