摘　　要：由于地质情况复杂,存在很多不确定因素,地质勘察资料不足以提供全部地层信息,而高边坡预应力锚索防护工程设计的可靠性直接影响到高边坡的安全和稳定,因而,为了达到设计的合理性,应结合地质勘察资料进行预应力锚索基本试验以确定最优的设计方案,达到安全、经济的目的。从预应力锚索基本试验着手,对如何进行试验准备,如何设定加卸荷载进行了深入讨论,并对试验结果进行了分析评价,确定了最优的锚索方案。Because of complex geological conditions and many uncertain factors, geological survey data are not sufficient to provide all the stratigraphie information, and the reliability of high slope prestressed anchor protection proiect design directly affects the safety and stability of high slope, thus , in order to achieve the rationality of design, it should be combined with the geological survey data for prestressed anchor basic test to determine the optimal design to achieve safety and economic purpose. This paper has an in- depth discussion on how to prepare the test and how to set the loading and unloading from the prestressed anchor basic test, and analyses and evaluates the test results, and determines the optimal anchor program.
