摘　　要：河道清淤疏浚中往往涉及到涉水施工作业,复杂的周边环境会给施工安全质量带来了风险,研究涉水清淤疏浚作业有重要意义。息安河河道水土流失比较严重,致使河道淤积严重,河底不断抬高,亟须进行清淤疏浚,来改善河流生态环境。针对上游段天然断面狭小且弯曲不顺,使河道排水不畅的问题,采用河道清淤疏浚采用梯形断面,下游河道淤积比较严重,河道中间以致出现了较大面积的滩地,采用河道清淤疏浚采用复式断面。重点针对涉水清淤施工阶段,使用节水绞吸船清淤施工、水上挖掘机采用纵向分条挖泥,而在每一条中采用横向排斗、依次前移的方法的清淤工艺方案。River dredging often involves water related construction operations,and the complex surrounding environment poses risks to construction safety and quality.Therefore,studying water related dredging operations is of great significance.The water and soil erosion in the Xi'an River is quite serious,resulting in severe siltation of the river and continuous elevation of the riverbed.It is urgent to carry out dredging and dredging to improve the ecological environment of the river.In response to the problem of narrow and uneven natural cross-sections in the upstream section,which leads to poor drainage in the river,a trapezoidal cross-section river dredging method is adopted.However,the downstream river channel is severely silted,resulting in a large area of beach land in the middle of the river.Therefore,a compound cross-section is used for dredging and dredging of the river channel.For the water dredging construction stage,water-saving suction dredgers are used for dredging construction,and water excavators are used for longitudinal strip dredging.And the dredging process scheme adopts the method of horizontal bucket arrangement and sequential forward movement in each line.
