广西崇左至靖西高速公路路线优化设计研究

山区修建高速公路路线选择对山区的经济发展至关重要，只有通过多方案的优选才能提出可行的工程方案。为此，结合广西崇左至靖西高速公路崇左至大新段对工可路线方案的优化、初步设计路线方案比选，根据项目特点制定路线选线原则，不同段落采取不同的控制重点，对公路路线优化设计进行研究。从而，提出了该工程路线设计的优化方案。

Route Optimization Design of Guangxi Chongzuo to Jingxi Highway

The route selection for construction of highway in mountainous area is of vital importance to the economic development of the area. The feasible engineering scheme can be proposed only through the optimization of multiple schemes. Hence, combining with Guangxi Chongzuo to Jingxi Expressway Chongzuo to Daxin Section, the working route plan is optimized and the preliminary design route plan is compared and selected. The route selection principle is formulated according to the characteristics of the project and different key points are adopted in different sections to study the route optimization design and the optimization scheme for the route design of this project is proposed.
