| 摘 要： | 阐述了锚碇区工程岩体的基本特征，并按国家岩体质量标准对工程岩体质量进行分，东锚碇体在虎门大桥主缆拉力作用下的稳定性分析分为物理模拟拔试验以及计算模型分析两部分，分析结果表明：在不考虑地地震力作用的情况下，锚碇岩体稳定系数大于２；随着地震加速度的增加，岩体稳定性急剧下降。 |

| Abstract: | In this paper, the basic characteristics of the rockmass in the anchoring area of the project is dealt with and the rock quality grade is carried out according to the National Rock Quality Grade Scale. The stability analysis of the rockmass in the east anchoring area is divided into two parts: the physical simulation of the pull test and the quantitative analysis of the computation model.The result of the analysis indicates that if the seismic force is not considered,the stability factor of the anchored rockmass is larger than 2 but it will decrease quickly with the increase of the seismic acceleration. |
