摘要
由于目前工程中涉及的有关抗浮锚杆的标准较多。各标准基于试验理论有差异,计算结果相差较大,这就造成了设计人员在实际工程中无所适从,查阅很多标准,最后却只能采用各标准计算结果包络设计收场。花费了大量的时间,并造成了不必要的浪费。本文以贵州某项目岩石地基为例,对比了目前常用的多部标准,分析它们的异同。并通过实际工程的分析对比,得出了贵州地区较硬岩上的岩石锚杆,锚固长度由构造锚固长度控制,锚杆的估算仅需要确定截面面积即可,大大节约设计师的时间,提高工作效率,供设计人员遇到类似工程时参考。
Due to the large number of standards related to anti-floating anchor involved in the current project,there are differences in test theories based on each standard,and the calculation results differ greatly.It leads to the designers in the actual project at a loss,despite consulting a lot of standards,designers ultimately can only use the results of each standard calculation envelope design.It takes a lot of time and causes unnecessary waste.Taking the rock foundation of a project in Guizhou as an example,this paper compares several commonly used standards and analyzes their similarities and differences.Through the analysis and comparison of actual projects,it is concluded that the anchoring length of rock bolts on harder rocks in Guizhou is controlled by the structural anchoring length,and the estimation of bolts only needs to determine the cross-sectional area.It can greatly save the designers'time,improve the work efficiency,and be used as a reference for designers when they encounter similar projects.
