| 摘 要： | 跨度是影响地下岩土工程稳定的重要参数之一，以往大跨度工程大多设置柱、墩式结构来进行减跨以保证稳定，从而严重影响工程的使用功能，本文通过对梁式桥和悬索桥的受力分析，探讨了减跨作用机理，提出了利用长深锚杆（索）实现地下工程减跨的支护理念，经工程的应用实践，证明该方法对提高深埋大跨度地下岩土工程的稳定效果是显著的。

| Abstract: | Span is one of the most important effective parameters of underground geotechnical engineering stability.Columns or piers structures are used in previous longspan roadway to reduce the roadway span and guarantee its stability,and these methods above affect the roadway' function seriously.Based on the mechanical analysis of the beam bridge and suspension bridge,we investigated the mechanism of reducing span and proposed the ideas of using deep long bolt(cable) to reduce span in underground works.The application has proven that the method has notable results for improving the deep long-span underground geotechnical stability. |
