岩锚的应用与展望

Practice and Further Develonment of Rock Anchorage

本文在简要介绍我国若干水库和水电站应用预应力岩锚的经验之后,讨论了应用岩锚技术中的若干问题,如被锚固岩体的稳定分析,锚索的张拉及应力控制,防止钢索腐蚀的措施及预应力随时间的损失等。最后展望可能应用岩锚的工程领域,并预期在水利水电建设中将得到越来越多的应用。

This paper describes briefly the Practice of rock anchorage in a number of water reservoirs and hydroelectric projects in China, and discusses some problems relating to the application of this technique. These problems are stability analysis of anchored rock masses, methods of applying the prestress and controlling of these stresses, protective measures against the corrosion of the steel wires, the losses of prestresses with time etc. The increasing uses of rock anchorage in the construction of water conservancy project and hydroeletric power plants are expected.
