Research On The Eco-friendly Road Construction And Geological Environment Issues

Transportation is the important field of building a "resource-saving and environment-friendly" society.On the one hand, modern road construction is not only an important symbol for rapid economic and social development, but also the guarantee of sustainable society development; on the other hand, enhancing the speed of highway construction causes the increasing consumption of resources, and ecological and human living environment get negative effect gradually. In this context, the study of eco-friendly road construction and geological environment Issues becomes an active demand.This study investigates the essence of eco-friendly road exemplified with the Daliu highway construction project, builds models for developing eco-friendly level evaluation of road, and summarizes relevant construction management and practical experience. The main results and innovations are as follows:1、With respect to the ecological problems that the highway construction process is facing, the current study makes depth analysis of the essential content of eco-friendly highway. The meaning of eco-friendly road is summarized as follows: a modern highway with a comprehensive construction program plan, standardized procedures and a reasonable construction of the building operation and management mechanism. It is described eco-friendly road with the theory that is different from traditional highway system, and the essence of eco-friendly road is analyzed scientifically from the macroscopic vision.2、Based on the theoretical system of eco-friendly road, this article focuses on the evaluation system study, to build eco-friendly road evaluation system from both the index system and the evaluation methods. Focused on the establishment of index system, the evaluation model of eco-friendly road was proposed from comprehensive analysis of the ecological landscape, soil and water conservation, and engineering geology. And the indicator framework was combed using the analytic hierarchy. To the evaluation methods, the expert scoring and non-dimensional method was conducted to determine the index value, and the analytic hierarchy to determine the index weight, fuzzy mathematical method to evaluate in this paper. 3、In the construction management of eco-friendly roads, the projects should focus on the temporary works, roadbed construction, traffic safety facilities, green landscape design, a full line of integrated planning. The current study focuses on the technical points in design, construction and operation of management stage of the sub-projects, clarify the organizational structure of construction, establishes a unified explicit construction technology program, security system, the implementation of responsibility for the organization department, builds up building management system, including the natural environment and ecological resources, protection of vegetation, erosion control, less environmental pollution.4、The paper selected Daliu highway project for the examples to evaluate its eco-friendliness comprehensively. The evaluation model of eco-friendly road was proposed from comprehensive analysis of the ecological landscape, soil and water conservation, and engineering geology. According to the evaluation results, a series practical eco-friendly road construction techniques were put forwarded for Daliu highway project.
