| 摘 要： | 某跨海大桥为一悬索桥 ,其主塔位于海中的岛礁上。因岛礁山体略显单薄 ,受数条断层及其他构造裂隙的影响 ,整体完整性较差。本文在大量现场地质资料调查基础上 ,系统结合上部结构荷载、风荷载 ,对工程边坡稳定性进行了分析研究 ,结果表明工程边坡整体稳定 ,但浅表部存在不稳定块体 ,并提出浅表部边坡相应的加固建议措施

| Abstract: | The main tower of a sea-crossing rope suspension bridge with a 1,650 meter span lies on an island. The thin mountain intersected by faults and other structural fissures result in low intactness of rock mass. Based on field geological investigations, the authors made a systematic analysis of the structure load and wind load and the slope stability. Results show that the slope is stable as a whole, but some unstable rock masses exist near the surface. To enhance stability of near surface rock masses, reinforcement measures are recommended. |
