| 摘 要： | 在山区高速公路修建隧道过程中经常会遇到的受地形限制,展线困难的地段,文章通过对此类隧道及围岩的地形和地质条件的受力分析进行论证和比选,最后采用小净距隧道的方案具有对路线、路基影响较小,且造价较低的优点,在山区公路的建设和设计过程中有着很广的应用前景。

| Abstract: | Construction of tunnel under mountainous expressway project may often encounter terrain restriction and difficult section. W ith a justification and comparison regarding the stress analysis for similar tun nels and for the topographic and geological condition of surrounding rock,a sma ll clear spacing tunnel has been adopted,as it is cheap and has less impact on the alignment and subgrade. It will have a broad application prospect in the con struction and design of mountainous highways. |
