Tunneling

2021-11-17

Characteristics of tunnel engineering:

  1. The whole project is buried underground, so engineering geology and hydrogeology conditions play an important and even decisive role in the success or failure of the tunnel construction.

    Should not only be detailed geological survey and exploration in exploration stage, as accurately as possible to grasp the tunnel project within the scope of the rock properties, the strength of rock mass, complete degree, ground stress field, the stable ability, the condition of groundwater state, the harmful gas and geothermal data, and according to these raw materials, preliminary selected appropriate construction methods, determine the corresponding construction measures and form a complete set of construction machinery.

    Moreover, due to the complexity of geological conditions and the limitations of exploration methods, it is still inev
