| 摘 要： | 某悬索桥采用隧道式锚碇加预应力锚索的复合锚固系统，与重力式锚碇相比，充分利用深层岩体的承载能力，可大幅降低工程造价，保护地表环境。经验性的设计方法和岩土工程参数的不确定性，使其设计风险和施工难度较大。主要介绍了复合式锚碇的设计思路与施工方法，为同类工程提供借鉴和参考。

| Abstract: | The compound tunnel anchorage with prestressed anchor cable is adopted in the construction of a suspension bridge. Compared with gravity anchorage, the compound anchorage makes full use of the bearing capacity of deep rock, hence may greatly reduce the cost and protect the environment. In view of the uncertainties in empiric design and geotechnical parameters which may cause high risks in design and difficulties in construction, this paper introduces the designing idea and construction of the compound anchorage. |
