摘要
京珠高速公路甘塘—太和段起于韶关甘塘止于广州太和镇,全线共有6座隧道,其中四座为上下行分离的三车道隧道,净宽达14.8m,开挖宽度达16.8m;另两座为上下行合建的六车道联拱隧道,净宽达31m,开挖宽度达32m。简要介绍了全线隧道设计的有关技术和处理原则。
The Gantang-Taihe section of Beijing-Zhuhai national trunk expressway starts from Gantang, Shaoguan to Taihe, Guangzhou. There are 6 tunnels in this section, among which four tunnels are three - lane highway tunnel with a net width of 14. 8m and an excavation width of 16. 8m, the other two are multiple - arch highway tunnels with a net width of 31m and an excavation width of 32m.
