A CONSTRUCTION METHOD OF COVER TYPE TUNNEL STRUCTURE FOR DECREASING BIASED EARTH PRESSURE ON CUT AND A COVER TYPE TUNNEL STRUCTURE THEREBY

摘要

The invention Tunnel excavation construction of the structure of a new type of construction method and excavation expression by such methods relates to the tunnel structure, the structure of the Tunnel excavation to prevent structural defects such as cracks in the tunnel structure which can especially occur under the influence of side slope embankment of earth pressure due to excavation Tunnel construction methods and structures that are constructed by such a method relates. Excavation Tunnel structure according to the present invention includes the steps of drilling a wonjiban, the excavation and construction comprising a tunnel structure in a part, comprising the step of covering the earth and sand to fill the upper part of the construction, and tunnel structures, the fill phase is a step of forming a fill slope more and, further comprising the tunnel construction structure is constructed by the construction method of excavation Tunnel structure comprising a vertical construction of the tunnel structure.
