地下综合管廊与人非共板路侧带断面的空间耦合优化

Spatial Coupling Optimization of Underground Utility Tunnel and Pedestrian and Non-mechanical-vehicle Integrated Slab Roadside Section

文章运用人体工程学和混合交通流冲突概率模型分析人非共板路侧带断面的断面形式和断面尺寸,提出满足最小通行要求的"极限尺寸"和满足日常通行要求的"推荐尺寸",建立5.5m^10m不同道路等级的人非共板路侧带断面尺寸组合表。以工程案例数据为基础,分析地下综合管廊的敷设位置、管线组合类型、管廊截面形状和尺寸,将地下管廊空间和地面人非共板路侧带断面空间进行耦合优化,提出地下综合管廊和地面慢行交通一体化的城市道路优化设计方案。

This paper first analyzes the cross-section form and section size of pedestrian and non-mechanical-vehicle integrated slab rodeside section by using ergonomics and mixed traffic flow conflict probability mode, puts forward "ultimate size" to meet the minimum traffic requirements and "recommended size" to meet the daily traffic requirements, and establishes a combination table of the pedestrian and nonmechanical-vehicle integrated slabroadside section size,with the road width ranging from 5.5 to 10 m for different road grades. This paper analyses the laying position, pipeline combination type, cross-sectional shape and size of underground utility tunnel based on some actual project data, performs the coupling optimization of underground utility tunnel space and pedestrian and non-mechanical-vehicle integrated slab rodeside section, and puts forward the optimized city road design scheme integrating underground utility tunnel with ground slow mode traffic.
