悬索桥以其构造简单、受力明确、跨越能力大、造型美观等优势，在我国高速公路建设中得到了广泛应用。锚碇作为悬索桥的基础，对整座桥梁的安全有着重要的作用。本文针对云南龙江大桥的地形以及全风化岩层的地质情况，选择适合的锚碇型式，进行结构分析和方案比选，确定最优的锚碇方案，以期给类似地形地质条件下的悬索桥锚碇设计提供参考。
懸索橋以其構造簡單、受力明確、跨越能力大、造型美觀等優勢，在我國高速公路建設中得到瞭廣汎應用。錨碇作為懸索橋的基礎，對整座橋樑的安全有著重要的作用。本文針對雲南龍江大橋的地形以及全風化巖層的地質情況，選擇適閤的錨碇型式，進行結構分析和方案比選，確定最優的錨碇方案，以期給類似地形地質條件下的懸索橋錨碇設計提供參攷。

Suspension Bridges have been widely used in highway construction of China, because of simple structure, clear stress condition, large span capacity and beautiful shape. As the foundation of suspension bridge, anchorage plays an important role in the whole bridge safety. In this paper, the suitable anchorage types are selected according to the topographic and geological conditions of Yunnan Longjiang suspension bridge , which is completely weathered rock stratum , and the optimal scheme of anchorage is confirmed through the structure analysis and scheme comparison. The results may provide reference for the design of suspension bridge anchorage with similar topographic and geological conditions.
