| Abstract: | This paper is based on small interval tunnel of eight lanes, According to the middle rock pillars plastic area and the influence which the first hole impact on after hole in displacement and in- ternal force, it discusses the reasonable value minimum interval under four lanes and small clear distance tunnel in various levels of surrounding rock. This paper have certain reference significance in design of large cross section tunnel. |

| Keywords: | eight lanes small clear distance plastic zone displacement and internal force areasonable value |
