包裹式加筋土挡墙在震区线侧下式车站的设计与应用

Design and Application of Packaged Reinforced Soil Retaining Wall at Low Lying Station in Seismic Region

以云南广通至大理新建双线快速铁路云南驿车站站台包裹式加筋土挡墙工程为例,对高烈度地震区线侧下式车站采用土工格栅包裹式加筋土挡墙进行设计与研究。结果表明:包裹式加筋土挡墙在高烈度震区、线侧下式站台、软土地基等条件下的应用相比传统支挡结构具有更好的经济和社会效益。

Taking the packaged reinforced soil retaining wall at Yunnanyi Station of the newly built Guangtong--Dali double-track fast railway as an example, the design and study was made herein to apply geogrid packaged reinforced soil retaining wall to the low lying station in high intensity seismic region. The result shows that, compared to traditional retaining structure, the application of packaged reinforced soil retaining wall on condition of high intensity seismic region, low lying station and soft soil foundation, may have better economic and social benefits.
