土工格栅加筋土挡墙地震响应分析

摘要
柔性网面土工格栅加筋土挡墙是一种新型支挡结构,其面墙为柔性钢筋网面,柔性网面与水平面成73°的坡面。通过大型的模型试验,研究了以红砂岩为填料在水平地震作用下柔性网面土工格栅加筋挡土墙的动力特性。输入地震波采用ELCE_NS地震波和HACH I_EW地震波,峰值分别为0.342g和0.183g。试验得出了柔性网面土工格栅加筋挡土墙在不同峰值的水平地震激励下的第1层、第3层、第5层墙顶面处的水平加速度、竖向加速度、水平动位移、竖向动位移峰值响应和沿墙高方向动应力峰值响应。通过对柔性网面土工格栅加筋挡土墙的结构分析和抗震试验,可以得出柔性网面土工格栅加筋挡土墙为优良的抗震结构,这为柔性网面土工格栅加筋挡土墙的抗震设计提供依据。
Flexible panel geogrid reinforced retaining wall is a new-block structure,whose panel is flexible reinforcing steel bar network of 73° with the horizontal plane into the slope.Large model tests were conducted on flexible panel geogrid reinforced retaining wall filled with red sandstone under horizontal seismic loading to investigate the dynamic response of wall.Input seismic waves were ELCE-NS and HACHI-EW,and the peaks were 0.342g and 0.183g,respectively.The horizontal acceleration,vertical acceleration,dynamic horizontal displacement,dynamic vertical displacement,dynamic stress peaks response of the first layer,the third layer,the fifth layer of flexible panel geogrid reinforced retaining wall were achieved by model tests under different peaks of horizontal earthquake incentives.The flexible panel geogrid reinforced retaining wall can be confirmed as excellent aseismatic structure by means of structural analysis and aseismatic experiment,which provides basis for the aseismatic design of flexible panel geogrid reinforced retaining wall.
