摘　　要：受河道采砂影响,大伙房水库输水工程穿越西马峰河处的河床不断下切,造成已建输水工程防护设施破坏,严重影响了输水工程的运行安全。为解决此问题,经过方案比选,选用了既能有效保护输水管线防护工程,又能适应河道日后进一步变化的混凝土预制方板桩防护方案,并详细介绍了该方案的设计指标和施工工艺,可为类似工程设计施工提供借鉴。The river bed of Dahuofang Reservoir Reservoir water conveyance project crossing Ximafeng River is continuously cut down under the influence of sand-mining in the river,thereby destructing the protection facilities of the constructed water conveyance project and seriously affecting the operation safety of the water conveyance project.The protection plan of concrete precast square sheet piles is selected in order to solve the problem,and it can not only protect the protection project of the water transmission line effectively,but also can adapt to the concrete precast square sheet pile protection plan which is further changed in the river in the future through comparison and selection of schemes.The design indicator and construction process of the plan are introduced in details,thereby providing reference for design and construction in similar projects.
