| 摘 要： | 将加卸载响应比（LURR）理论引入边坡动力稳定分析研究中,建立边坡在地震作用下的加卸载响应模型,通过对边坡动力加卸载响应规律的研究,提出以代表边坡系统整体响应的加卸载响应度（LURD）代替边坡稳定分析传统方法中的安全系数,将边坡的变形分析和稳定性评价有机结合,探讨边坡动力稳定评价的新方法,并给出边坡在动荷载作用下的稳定性评价问题的解答。以马家岩水库右岸边坡为例,采用所提出的新方法进行计算,并与拟静力法、有限单元法和Newmark滑块法的计算结果进行对比,验证所提出方法的合理性及正确性,证明新方法可同时进行变形和稳定分析,较传统的动力分析方法精度更高。 |

| Abstract: | The theory of load-unload response ratio(LURR)is introduced to analyze dynamic slope stability.The LURR model of slope is established by studying laws of load-unload response ratio of slope under seismic load;and a concept of load-unload response degree(LURD)is suggested to substitute the factor of safety.With this concept,a new method of dynamic slope stability is explored;and deformation analysis and stability evaluation are well combined.Taking the right bank of Majiayan reservoir for example,a dynamic analysis is performed using the suggested method.Compared the calculating results with pseudo-static method,finite element method and Newmark sliding block method,it is verified that the presented method is reasonable.The new method has priority to traditional dynamic analysis method in precision;and it can carry out deformation and stability analysis at the same time. |
| Keywords: | slope engineering load-unload response ratio(LURR) dynamic response stability analysis |
