| 摘 要： | 结合汶川震区调查资料,利用大型振动台模型试验,分析了碎石土填料的岩石场地重力式挡土墙的地震土压力及其分布规律,并以此对我国现行铁路、公路抗震规范做合理性讨论和细化.研究发现,地震作用下,挡土墙的动土压力沿墙高呈单峰曲线状分布,且60%～80%集中作用于挡墙中部;随着地震峰值加速度的增加,地震土压力分布逐渐偏离现行振震设...

| Abstract: | After the occurrence of a destructive earthquake,according to building and structure damage characteristics,it is important and imperative to revise the current seismic design codes.Combining with the seismic damage investigation in Wenchuan earthquake,this paper analyzes the seismic earth pressure of crushed gravel filled gravity retaining wall(GRW)and distribution of earth pressure by using large-scale shaking table model test.Based on the above analysis,reasonable discussion and refinement are made on cu... |
