城市滨水慢行专用桥设置研究

Study on the construction of urban waterfront bridge for slow traffic

城市滨水区作为城镇最开放的公共空间之一,为慢行活动提供清新的空气、充足的阳光、天然的水环境等丰富的自然条件。同时随着越来越多的高品质滨水地区的开发,水系两岸成为城市新的活力中心,两岸滨水空间的融合发展态势逐渐增强,游憩、休闲、锻炼、通勤、购物等跨水系慢行需求不断增多,对出行体验与安全需求不断增强,这就与传统跨水系慢行出行主要依托传统干线桥梁模式产生冲突。同时我国大多数城市在慢行系统交通规划中,其慢行区设置常常以河为界,桥梁虽为慢行过河的必经通道,但在慢行规划中往往被忽视。因此旨在通过分析滨水两岸间的慢行出行特征,研究慢行专用桥设置的适宜尺度、密度与断面宽度,以及所需具备的交通与文化、景观相融合的特点。

Urban waterfront,as one of the most open public spaces in the town,provides abundant natural conditions such as fresh air,sufficient sunlight and natural water environment for slow walking activities.At the same time,with the development of more and more high-quality waterfront areas,the two sides of the water system have become the new vitality center of the city,and the integrated development trend of the waterfront space on both sides is gradually enhanced.The demand for slow travel across the water system,such as recreation,leisure,exercise,commuting and shopping,is constantly increasing,and the demand for travel experience and safety is constantly enhanced.This is in conflict with the traditional slow travel across water systems,which mainly relies on the traditional trunk bridge mode.At the same time,in the traffic planning of the slow traffic system in most Chinese cities,the setting of the slow traffic area is often bounded by rivers.Although the bridge is the only way to cross the river in slow traffic,it is often ignored in the slow traffic planning.Therefore,this paper aims to analyze the characteristics of slow travel between the two banks of the waterfront,and study the appropriate scale,density and section width of the special bridge for slow traffic,as well as the required characteristics of the integration of traffic,culture and landscape.
