Abstract

When railway and highway traffic projects pass through scenic and historic interest areas, several issues, such as sewage, noise, vibration, ballast disposal, and dust, are introduced. To address these issues, a case study of the new Badaling tunnel and the Badaling Great Wall station project of BeijingZhangjiakou highspeed railway is conducted, and the potential environmental pollution factors caused by the construction and operation of the project in scenic and historic interest areas are systematically analyzed. Further, the principles and technical means for environmental protection are presented from the design and construction perspective. The results are as follows: (1) The undercrossing scheme is feasible for railway and highway projects in scenic and historic interest areas. (2) The environmental protection indices can be satisfied by adopting several techniques including hidden elimination design of entrance and exit of station, drainage system by sewage diversion, longdurability structure design, microshock and microdamagecontrolled blasting technology, dust removal technology using highpower tunnel air, wastewater treatment technology using a biological aerated filter, and ballast recycling.
