浅议平溪河李树至洞坪段河道治理工程设计

On design of river governance engineering of Pingxi River from Lishu to Dongping Section

平溪河李树至洞坪段经多年水流冲刷,部分临河护岸难以发挥防洪功用,急需河道治理工程设计。本文依据禾滩水文站实测水文观测数据,对工程区进行设计洪水计算、设计水面线计算、施工期洪水计算。同时,选定设计基准年为2013年,堤防、护岸工程级别为5级,重点对治导线布置、提防方案选定、重力式浆砌石挡墙断面设计等河道治理工程设计中的核心内容进行详细阐述,可为类似工程提供借鉴。

Pingxi River from Lishu to Dongping Section suffers from water scouring for many years. A part of riverside revetments cannot play the role of flood control easily. It is urgent to design river channel governance engineering. In the paper, designed flood calculation, designed flow profile calculation, and construction period flood calculation are implemented in the engineering area according to measured hydrology observation data of Hetan hydrological station. Meanwhile, the designed benchmark year is selected as 2013. Dike and revetment engineering level is 5. Core contents in river governance engineering design are described in detail mainly, including regulation line layout, embankmeni plan selection, gravity slurry masonry retaining wall cross section design, etc., thereby providing reference for similar projects.
