摘要
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 pulling test of 1：12 anchorage model of Siduhe Suspension Bridge, and the deformation ＆ strain distribution characteristics of surrounding rock of the bridge anchorages am simulated and evaluated on the basis of the observed data. Permanent safety coefficient and instantaneously limited load-bearing capacity of anchorage am obtained. The test results can be used for numerical modeling analysis for the next step.
