Construction Application of Dual-Mode Shield Tunneling Machine in Composite Strata
In complex terrain and harsh geological conditions,ordinary shield tunneling machines can no longer meet the requirements.The emergence of dual-mode shield tunneling machines can solve the problem of construction in composite strata.Taking Jinan Metro Line 6 as the background,this paper analyzes the construction application effect of double mode shield tunneling machine in composite strata.this dual-mode shield Tunneling machine combines the construction advantages of TBM and earth pressure balance shield machines,and can switch between two modes according to geological characteristics.After verification,it reduces risks during the construction process and greatly improves construction efficiency.
