黄河宁夏段河道整治工程的护根材料

摘要

For the geological conditions of the Yellow River in Ningxia reach,we reviewed the structure types and characteristics of the mulch mate-rials in the different periods used in the river training works such as volume broom with grass and soil,weight-bearing wooden frame tetrahedron, concrete tetrahedral,four corners of the concrete body and lead wire gabion,analyzed the practical application of various materials and the advanta-ges and disadvantages and considered that the mulch material of four corners of the concrete body should be selected for the section from Zhongwei to Rencundu and gabion should be chosen for the section from Rencundu to Shizuishan.%针对黄河宁夏段的河道地质条件，回顾不同时期应用于河道整治工程中草土卷埽、木架附重四面体、混凝土四面体、混凝土四角体、铅丝石笼等护根材料的结构型式和特点，分析各种材料的实际应用效果和优缺点，结果表明：中卫至仁存渡河段的护根材料宜选用混凝土四角体，仁存渡至石嘴山河段宜选用格宾石笼。
