Some thoughts on network planning and construction of urban rail intersection

Zhengyu Lu


A case study of Shanghai Rail intersection network planning , put rail into network era , should innovate in planning design concepts , moderately ahead of plan , Build intensive , Multi-level rail intersection system , and strengthen interaction and land control with urban planning . advocates rail intersection with station Core body , Implement the networked development phase the innovative design of station sustainable development . The summarizes the construction of rail-intersection projects in soft soil area represented by Shanghai technology , construction methods for hub projects and protection techniques and measures for urban environment , Application Prospects for construction of new technologies for rail-intersection engineering
