| 摘 要： | 对高为33～55 m的双面加筋土挡墙进行离心模拟试验,测得的面板上土压力分布从上至下呈先增后减型。基于加筋土挡墙的破坏模式,对于面板侧向土压力分布进行探讨。综合分析本次试验结果和现场测试,从理论上分析了加筋土挡墙面板上侧向土压力的分布,并对目前《公路加筋土工程设计规范》中基于侧向土压力进行设计的方法提出质疑。

| Abstract: | Double-face reinforced retaining walls of 33.0 m to 55.0 m high are modeled on a centrifuge.From the top to the bottom of retaining wall,the earth pressure acting on the facing panels increases with depth and then decreases with depth.The distribution of lateral earth pressure is explained according to the failure modes of retaining wall.Furthermore,the distribution of lateral earth pressure is illustrated based on the results of site testing.It is suggested that the actual code on how to calculate the quantity and the length should be modified. |
