The Hong Kong And Macao Expressway Shijiazhuang To Axis Section Reconstruction Project Construction Scheme Comparison Research As A Whole

This paper elaborated the highway projects of the basic principles of general construction scheme selection and highway reconstruction project of expansion mode and expansion mode, the relationship between the case of reference for the similar engineering construction at home and abroad, in view of the characteristics of Shi An highway, according to the different form of highway reconstruction, respectively for Shi An high speed main line, the main control points such as the reconstruction and the reconstruction scheme of the section has carried on the comparative study.Through the demonstration research, this paper has formed a "stitching on both sides, and secondly local separation and local expansion" Shi An highway reconstruction project overall expansion plan. Lines extended section adopts stitching on both sides to give priority to local expansion for the eight-lane highway on both sides of the separation way; Shijiazhuang local expansion, new 8 lanes, synchronization to overhaul maintenance of existing path, shijiazhuang loop synchronous construction B line; Xingtai section splicing expansion of 8 lanes on both sides; Handan city transit section based on both the Shi An high-speed broaden the converted into 8 lanes, construction of handan southeast ring at the same time, the new four lanes. Road capacity in the new line construction scale, shijiazhuang 8 driveway, handan four lanes.In this paper, the general expansion Shi An highway reconstruction project scheme demonstration research has certain practical significance, for the domestic operating highway reconstruction project overall expansion scheme has provided the very good demonstration and practical significance.
