摘　　要：黄河宁夏段因受特殊的自然地理条件影响,河势摆动频繁,塌岸毁堤现象严重,威胁着两岸人民生命和财产安全。多年来,在岸坡防护工程中采用铅丝石笼,存在铅丝易锈蚀、断裂等问题。为改善传统铅丝石笼材料在工程应用中的缺陷,采用土工格栅石笼替代传统材料。以黄河中卫段岸坡防护工程为例,进行现场试验及变形监测,分析土工格栅石笼在工程应用中的防护效果,结果表明:变形绝对值小于40 mm的测点占测点数的94.4%,变形以微弱沉降为主,与传统材料相比,土工格栅石笼具有抗冲能力强、抗腐蚀性强等优点,具有很好的应用前景。Due to the special natural geographical conditions in Ningxia section of the Yellow River,the channel swings frequently and collapse and ruined levee are seriously,threatening the safety of the life and property of the people on both sides.Over the years,in slope protection engineering,people use the traditional stone cage wire material and concrete corners,but there is wire corrosion fracture of the shortcomings.In order to improve the traditional stone cage wire material defects in the application,we introduced and used the geogrid gabions technology instead of the traditional material.Taking Zhongwei Yellow River section of slope protection works for an example,it conducted the field test monitoring and deformation and analyzed the protective effect of geogrid gabion in engineering applications.The results show that the deformation is less than the absolute value 40mm of measuring point accounts for 94.4%of the measuring points and the deformation mainly show weak settlement.Comparing with conventional materials,geogrid gabions have the advantages of strong resistance to impact and corrosion and have a good prospect of application.
