介绍了四渡河特大悬索桥隧道锚碇1∶12现场模型试验，根据试验结果研究了锚碇周边岩体的时效变形形态及应变分布特征，得到了隧道锚碇的长期安全系数及瞬时极限承载力。测试结果为下一步开展的数值理论分析提供依据。

This paper presents the in -situ p ulling test of 1∶12 anchorage model of Siduhe Suspension Bridge, and the deformatio n & strain distribution characteristics of surrounding rock of the bridge anchor ages are simulated and evaluated on the basis of the observed data. Permanent sa fety coefficient and instantaneously limited load -bearing ca pacity of anchorage are obtained. The test results can be used for numerical mod eling analysis for the next step.
