| 摘 要： | 神土隧道为双向四车道连拱隧道形式,由于其处于全风化—弱风化变质砂岩或花岗闪长岩内,工程地质条件差,特别是上陵端洞口段地形复杂,偏压严重,设计和施工难度均较大。文章主要介绍其洞口偏压段的处理、复合式连拱隧道的设计与施工工法,可供类似工程参考。

| Abstract: | The double-arch 4-lane Shentu tunnel is situated on the Yuegan expressway in Guangdong province.As the tunnel is embedded in the fully or weak weathered metamorphic sandstone and granodiorite strata,the engineering geologic condition is poor.Especially on the portal section at Shangling end,the terrain is complicate and side pressure is evident that cause difficulties in both design and construction.This article summarizes the treatment measures on the side-pressure section,the design and construction of the composite double arch tunnel,which can be taken for reference by similar projects. |
