Qualitative Evaluation of Safety

定性评价安全

Consider the safety implications of a barrier's location.

考虑障碍的位置，影响安全。

Reinforcement additions add weight to the barrier which can be a problem on structure-mounted barriers.

加固增加加重，屏障可以是一个结构问题上安装的障碍。

Consider the safety implications of a barrier's type.

考虑障碍的类型的安全问题。 

Consider barrier protective devices as part of the overall barrier design.

考虑整体设计的一部分障碍屏障保护装置。

视距

Sight Distance

Sight distance concerns along horizontal curve sections of highways and at locations where a barrier terminates near a highway's or ramp's intersection with another roadway.

沿公路平曲线路段的视距关注和地点附近的一个障碍终止公路的或坡道的交集与另一巷道。

Emergency Access

紧急通道

Barrier Overlap

垒叠

Ensure the acoustical requirements of such overlaps are met.

确保这些重叠的声学要求都得到满足。

Ensure the safety of pedestrians within or near the gap.

确保内或附近的差距行人的安全。

Access Doors

访问门

Doors need to be designed so as to be acoustically "sealed" when closed.门需要进行设计，以具有声学“密封”时关闭。

Emergency Access for Utilities

紧急通道的工具

When not in use, doors should be locked to avoid unauthorized access.在不使用时，应锁好车门，以避免未经授权的访问。

Fire Safety消防安全

Ensure the correct size connection and ensure the capability of withstanding the thrust loads generated by the force of the moving water in the hose lines.

确保正确的大小的连接，并确保承受的推力由移动水的软管线力量产生的负载能力。

Ensure the capability of withstanding thrust loads, and keep in mind that the closure caps and their retaining chains can become the target of theft and vandalism.

确保承受推力负荷能力，请记住，关闭上限和保留一样可以成为盗窃和破坏的目标。

A device is needed to seal the opening when it is not in use in order to avoid acoustic degradation and to restrict the passage of small animals.

需要的设备密封开幕时，不使用，以避免声退化和限制小动物通道。

Note that identification signs are required on both sides of the barrier to enable the proper coordination of emergency personnel.

请注意识别标志上的障碍，双方必须使应急人员进行了妥善的协调。 

Glare

眩光

Tilted Walls倾斜的墙壁

Walls tilted for acoustical reasons may cause glare.

对声学的原因可能会造成眩光墙倾斜。

Anti-glare Screens

防眩屏

Dependent on the type of material used, the screen may alter the acoustical characteristics of the roadway.

在用的物料种类依赖，屏幕可能会改变巷道的声学特性。

Shatter Resistance粉碎性

Particular concern should be given for barriers on structure overpassing another highway causing potential injury to nearby vehicles, pedestrians.

特别应关注的结构立交桥的另一条潜在的伤害，造成附近的车辆，行人的障碍。

Consideration should be given to the potential shatter resistance of transparent and plastic barrier materials.

应考虑到透明塑料阻隔材料可能打破阻力。

Ensure that the barrier can withstand the additional loads that may result from plowed snow being both thrown and piled up against the barrier.

确保该屏障能够承受额外的负荷，可能导致被雪犁抛出都堆积了反对屏障。

Maintenance维修

Place barriers a sufficient distance from the travel way to ensure adequate space for storage of plowed snow.

广场屏障的旅行方式，以确保对耕雪储存足够的空间，已有足够的距离。
