  “远看桥形,近看栏杆”,栏杆是桥梁的门面,是桥梁建筑美学设计体系中重要的一部分,富有浓厚时代气息的栏杆不仅美化了城市及周围环境,也衬托了大自然的优美景观。栏杆作为桥梁的重要组成部分,你是否其真正的作用呢?

       随着时代发展,建桥技术的不断提高,桥梁栏杆也在不断变化。21世纪,人们期待着桥梁护栏的景观设计更具有现代化、个性化、人性化,同时蕴含着民族、文化、地域的气息,从而美化人们的生活环境。

一般来说,桥梁护栏的目的是为了防止失控车辆越出桥外,具有使车辆不能突破、下穿、翻越桥梁以及美化桥梁建筑的功能。从古至今,在桥梁的历史上,的确栏杆很长的一段时间内主要作用都是美化和防护的作用,因为那时的桥梁主要以木、石等材料建成,没有今天那么多的车辆,桥梁护栏很好的解决了人们在过桥时的安全问题。 但是随着社会的发展,车辆急剧增多,桥梁跨度不断增大,桥梁建设须考虑成本因素,首先要优先考虑大桥的桥墩、主塔、索缆、桥面等主体结构,而防撞栏、护栏等都属于辅助结构。因此,在投资有限的情况下,其次,才能考虑辅助设施。大桥要保证的是主体结构的安全,桥梁护栏的功能也有了些许变化。现在桥梁护栏主要、比较经常的作用是视觉诱导,就是用来警示护栏的里面是桥面、外面是高空,提醒大家保持距离、注意远离。

当然,这并不是说可以忽视辅助设施的安全投入。要知道,大型车辆如果高速或大攻角(接近垂直方向)冲撞护栏,撞击力超过护栏的防护能力极限,护栏也难以保证车辆不会冲出桥外。

       所以,这也提醒司机朋友们,开车一定要注意行车规范,安全驾驶。

"Looking at the shape of the bridge from a distance, looking at the railings from a close perspective", railings are the facade of the bridge and an important part of the aesthetic design system of bridge architecture. Railings with a strong sense of the times not only beautify the city and its surrounding environment, but also set off the beautiful landscape of nature. As an important part of a bridge, do you really use railings?

With the development of the times, the continuous improvement of bridge construction technology, bridge railings are also changing. In the 21st century, people expect the landscape design of bridge guardrail to be more modern, personalized and humanized, and at the same time contain the national, cultural and regional flavor, so as to beautify people's living environment.

Generally speaking, the purpose of bridge guardrail is to prevent out of control vehicles from crossing the bridge, which has the function of preventing vehicles from breaking through, underneath, crossing the bridge and beautifying the bridge building. From ancient times to now, in the history of bridges, it is true that the main function of railings is to beautify and protect for a long time, because the bridges at that time were mainly made of wood, stone and other materials, not so many vehicles today, and the bridge guardrails solved the safety problems of people when crossing the bridge. However, with the development of society, the number of vehicles is increasing rapidly, and the span of bridge is increasing. The cost of bridge construction must be considered. First of all, the main structure of bridge pier, main tower, cable, bridge deck and so on should be given priority, while the anti-collision barrier, guardrail and so on are auxiliary structures. Therefore, in the case of limited investment, secondly, auxiliary facilities can be considered. The first thing to ensure for the bridge is the safety of the main structure, and the function of the bridge guardrail has changed a little. At present, the most important and frequent function of bridge guardrail is visual guidance, which is used to warn that the inside of guardrail is the bridge deck and the outside is the high altitude, so as to remind everyone to keep away from it.

Of course, this is not to say that the safety input of auxiliary facilities can be ignored. It should be noted that if a large vehicle collides with a guardrail at a high speed or at a high angle of attack (close to the vertical direction), the impact force exceeds the limit of the guardrail's protection ability, and the guardrail is also difficult to ensure that the vehicle will not rush out of the bridge.

Therefore, it also reminds drivers that they must pay attention to driving standards and drive safely.
