高边坡防护工程预应力锚索设计参数及施工工艺的合理性直接影响到高边坡的稳定和安全。本文以西南某高速公路高边坡防护工程预应力锚索基本试验为案例,通过试验结果确定防护锚索的极限承载力,验证锚索设计参数与施工工艺的合理性。 The design parameters of prestressed anchorage cable and the rationality of construction technology of high slope protection project have a direct impact on the stability and safety of high slope. In this paper, a case study of the prestressed anchor cable for high slope protection project of a highway in Southwest China is taken as an example. The ultimate bearing capacity of the anchorage cable is determined through the test results, and the rationality of the design parameters and construction technology of the cable is verified.
