【摘要】：近两个世纪以来,混凝土安全护栏的现场建造技术并未发生本质改变,奥地利DELTA BLOC国际公司通过大量碰撞试验和深入研究,最近提出了新一代混凝土安全护栏技术。技术报告提出了在现代技术水平下新一代混凝土安全护栏的正确使用方法。在大多数欧洲国家,中央分隔带建造并采用了大量混凝土安全护栏,其优势是混凝土护栏安全性极高、养护极少、性价比优良,车辆碰撞后的动态横向位移外延值与横向位移较小,被认为是特别安全高效的护栏安全防护技术。因为混凝土护栏具有相当大的体积和刚度,故轻型车辆碰撞后损坏较为严重,对司乘人员的防护处在危险区间,在欧洲曾引起了广泛的争议,但是这些缺点由于建造投资压力似乎是可以被接受的,也是可以被克服和忽略的。
[Abstract]:In the past two centuries, the construction technology of concrete safety guardrail has not changed substantially. DELTA BLOC International Company of Austria has conducted a large number of impact tests and in-depth research. A new generation of concrete safety guardrail technology has recently been proposed. The technical report suggests the correct use of the new generation of concrete safety guardrails at the modern technological level. In most European countries, A large number of concrete safety guardrails are constructed and used in the central separation zone. The advantages of the concrete guardrail are that the concrete guardrail is extremely safe, little maintenance, good performance-price ratio, and the dynamic lateral displacement extension value and lateral displacement are small after vehicle collision. The concrete guardrail is considered to be a particularly safe and efficient barrier protection technique. Because the concrete guardrail has a large volume and stiffness, the light vehicle is damaged more seriously after the collision, and the protection of the crew is in the danger zone. There have been widespread controversies in Europe, but these shortcomings seem to be acceptable, overcome and ignored because of construction investment pressures.
