由长江科学院岩土重点实验室工程技术学科承担的云南普立特大桥隧道锚抗拉拔模型现场试验已于近日完成,该项试验按照相似原理进行模型制作,对试验过程中产生的变形,尤其是围岩破坏过程和破坏面形态进行跟踪测试,为认识普立特大桥隧道锚变形破坏过程,研究隧道锚力学机理提供了试验依据。该研究项目系云南省交通运输厅科技项目《高山峡谷地区 An on-site test of anchorage-pull-pull model of Yunnan Pulitng Bridge undertaken by Engineering Laboratory of Geotechnical Key Laboratory of Yangtze River Scientific Research Institute has been completed recently. The test is based on a similar principle to make the model. The deformation during the test, especially It is the follow-up test of the failure process of the surrounding rock and the morphology of the failure surface. It provides a test basis for understanding the anchor deformation and failure process of the tunnel and researching the mechanics of the tunnel anchor. The research project is the Department of Transportation of Yunnan Province Science and Technology Project "Alpine Canyons area
