Effective ecological environment protection is crucial
for constructing long tunnels in the Qinghai-Xizang plateau and high-altitude areas. Based on strategy of green and low-carbon development, the authors evaluate and analyze the application
effect of green ecological environmental protection technology in long tunnels
from the aspects of tunnel green construction, waste resource utilization,
wastewater treatment, material and land conservation, energy-saving and emission reduction. The results indicate the following:
(1) Based on the construction process and characteristics of long tunnels, the
idea of "respecting nature, conforming to nature, and protecting
ecology" should be fully implemented; the concepts of early entry and late
exit of tunnel entrance engineering, highly mechanized construction, and
separation of clean and dirty water in tunnels should be further deepened. (2)
Based on the principles of "work reduction, resource utilization, and
intensification", the comprehensive utilization of tunnel waste resources
saves the land occupied and reduces the impact on the surrounding environment.
(3) The green, low-carbon, energy-saving and emission reduction strategy should be strengthened, and
various environmental and water conservation measures during construction
period should be enhanced to minimize the impact of construction on the
surrounding ecological environment.
