| Abstract: | Reversal bamboo-cutting bell mouth portal、the capping eaves type portal、wall tunnel portal are used for capacity expansion project in rebuilding lou shao railway.Based on safety、pro-environment and cosiness of passengers,the capping eaves type portal is more used than other portals.Reversal bamboo-cutting bell mouth portal is used in steep land form of some tunnel exits.Based on landform and geological situation,open excavation method、undermining method of open hole are used after mulling stabilizing factors of portals,which makes the designing of portals more perfect. |
