枢纽互通式立交改建方案优化

随着全国和各省高速公路网规划的调整,高速公路之间相互交叉的枢纽互通式立交日益增多,对现有枢纽互通式立交的改建工程也越来越多.如何针对现有枢纽互通式立交的控制因素,结合地形、地物、地质等条件,深入进行方案比选,得到经济合理的互通式立交改造方案已成为互通式立交设计中的重要课题.以祥云寺枢纽互通式立交为例,探讨了枢纽互通式立交改建设计的思路和方法.

Scheme Optimization of Terminal-Interchange Reconstruction

Along with adjustment of the national and provincial expressway network planning, terminalinterchanges among expressway are increasing, and reconstruction projects of existing terminal-interchanges are more and more. How to make depth scheme comparison aiming at the control factors of existing terminal-interchange and combining with the terrain and surface features and geological conditions for obtaining an economic and reasonable reconstruction scheme of interchange becomes the important subject in the design of interchange. Taking Xiangyun Temple terminal-interchange as an example, the paper explores the ideas and methods of terminal-interchange reconstruction design.
