电缆桥架的荷载
Load of cable bridge
电缆桥架的荷载分为荷载、动荷载和附加荷载。
The load of cable bridge is divided into load, dynamic load and additional load.
静荷载是指敷设在电缆桥架内的电缆种类、根数、每根的外径重量/单位长度,按电缆敷设的不同路由分别列表统计。
Static load is the type of cable, the number of roots, the weight of the outer diameter per root, and the unit length of the cable laid in the cable bridge.
动荷载是指电缆桥架安装和维护过程中施工维修人员的重量。对于轻型电缆桥架,一般不考虑动荷载,即不允许在桥架上站(行)人,如果需要考虑站人,则应将跨距适当缩小。附加荷载仅在室外是指冰雪、风和电磁力所形成的荷载,它与安装场所的地区自然气象条件和带电体的性质有关,设计中应根据各种条件加以计算。
Dynamic load refers to the weight of construction maintenance personnel during the installation and maintenance of cable bridges. For light cable bridge, generally do not consider dynamic load, that is, it is not allowed to stand on the bridge. If we need to consider the station, we should shorten the span. The additional load only in the outdoor is the load formed by ice, snow, wind and electromagnetic force. It is related to the natural weather conditions and the nature of the electrified body in the area of the installation, and the design should be calculated according to various conditions.
