在常州施工铝艺别墅庭院护栏(围栏)的最终目标是希望通过护栏的保护作用，防止造成严重后果的事故。无论何种常州铝艺别墅庭院护栏(围栏)形式其最重要的性能是安全性。其次要考虑护栏的美学及对驾驶员的心理影响，通过护栏的设置给道路使用者增加舒适感和安全感，能在视觉上自然地诱导驾驶员的视线，保持公路线形的连续性，并减少对危险路段产生的恐惧心理。为达到上述目的，对铝艺别墅庭院护栏(围栏)的性能要求如下：

The ultimate goal of the construction of yard guardrail (fence) of aluminium art villa in Changzhou is to prevent serious consequences through the protection of guardrail. No matter what kind of Changzhou Aluminum Art Villa courtyard guardrail (fence) form, its most important performance is safety. Secondly, we should consider the aesthetics of the guardrail and its psychological impact on drivers. By setting the guardrail, road users can increase comfort and security, which can visually and naturally induce the driver's vision, maintain the continuity of highway alignment, and reduce the fear of dangerous sections. In order to achieve the above objectives, the performance requirements of the courtyard guardrail (fence) of the Aluminum Art Villa are as follows:

一、结构适应性要求 车辆不能撞断、下穿或跃过护榉以防止车辆驶出路外或阉入对向车道，护栏能使碰撞车辆平顺地改变方向，防止护栏的部件在碰撞后穿人车内客舱或对其他交通构成危险。这就是护栏的强度要求。

1. Structural adaptability requires that the vehicle should not crash, cross or jump over the beech to prevent the vehicle from driving out of the way or into the opposite lane. The guardrail can smoothly change the direction of the collision vehicle and prevent the parts of the guardrail from penetrating the passenger cabin or posing danger to other traffic after the collision. This is the strength requirement of the guardrail.

二、车内乘员的危险性要求 在碰撞期间和碰撞之后，车辆应保持直立，碰撞时产生的减加速度不使乘员受到伤害，当车辆碰撞护栏时，护栏应产生一定量的弹、塑性变形来吸收碰撞能量，减少车辆损坏，并能延长碰撞过程的作用时间，以确保车内乘员的安全。

2. The danger of passengers in a vehicle requires that the vehicle should be upright during and after the collision. The acceleration reduction caused by the collision does not cause the passengers to be injured. When the vehicle collides with the guardrail, the guardrail should produce a certain amount of elastic and plastic deformation to absorb the collision energy, reduce the damage of the vehicle, and prolong the action time of the collision process, so as to ensure the safety of the passengers in the vehicle.

三、车辆的轨迹要求 车辆碰撞护栏后，车辆以较小的驶离角回到原来的行驶方向，车辆的轨迹和最终停止位置不影响在其他车道行驶的车辆。

3. Vehicle trajectory requires the vehicle to return to the original direction with a small departure angle after colliding with the guardrail. Vehicle trajectory and final stop position do not affect the vehicle traveling in other lanes.

最后一点就是对行使车辆具有视线诱导效果。每种形式的铝艺别墅庭院护栏(围栏)具有其本身的特点和适用条件。

The last point is that it has the effect of line-of-sight guidance for the driving vehicle. Each form of aluminium art villa courtyard guardrail (fence) has its own characteristics and applicable conditions.
