城市道路交叉口人行地道设置与覆土深度设计

On Urban Road Intersection Pedestrian Lane Setup and Covering Depth Design

以乌鲁木齐市新华路为例,对比行人过街设施形式的特点,在充分调查交叉口情况的基础上,提出交叉口地下人行地道的设置条件,分析不同覆土深度的适用条件。通过地道覆土深度方案比较,论证推荐覆土深度采用4 m。再进行了方案优化,确定采用2个台阶式平面的地道布局。

Taking Xinhua Rd.in Urumqi for example,on the basis of a feature comparison of different pedestrian crossing street facilities types and a detailed survey of the intersection traffic condition,the setup criteria of intersection underground pedestrian lane is proposed with the applicable condition analysis of different covering depths.Through the tunnel covering depth plans comparison,the depth of 4 m is argued and recommended.And moreover,the plan is optimized and the setup of two-step-typed plane tunnel is adopted finally.
