Abstract

The following key innovative technologies adopted for Beijing-Zhangjiakou high-speed railway are introduced: (1) In the construction of Qinghuayuan tunnel, the prefabrication and assembly technology is adopted for the under-track structure of the tunnel and assembly robots are developed and applied, which ensures the construction schedule, meets the safety requirements, saves labor costs, and has achieved significant economic and social benefits. (2) A visualized and intelligent construction management and monitoring platform is built during the construction of the shield-bored Qinghuayuan tunnel, which realizes visualized and real-time prediction and analysis of risks and ensures the safety of tunnel construction. (3) Automatic coatingtechnology is adopted for the outside enveloping waterproofing of Donghuayuan tunnel, which greatly improves the working efficiency and reduces the danger of the operators. (4) Cross-section quality management system based on 3D laser scanning technology is adopted for New Badaling tunnel and Zhengpantai tunnel, which meets the needs of process control and early warning for tunnel cross-section measurement.

Key words： BeijingZhangjiakou highspeed railway; tunnel; intelligent construction; prefabrication and assembly technology; BIM technology; automatic construction
