摘要
详细分析了《通信铁塔标准图集》中所提供的塔型,从用钢量、占地面积和承载能力等方面对标准塔型进行了分析,给出了相应设计建议:景观塔,双轮塔在经济实用性和安全性上都要优于灯杆塔;当高度和风压相同时,三管塔要比单管塔更为经济,2种塔型都具有较高的安全性储备;相比于三管塔,角钢塔的安全储备更高,但其占地面积也更大,可在风压较大或建筑面积较宽裕的地区使用。
Al the types of steel-tower in the communication engineering steel-towers drawing col ection were compared and analyzed from the aspects of the steel consumption, construction area and resistance. The suggestions for the design and selection of steel tower are provided. The research indicates that regarding to two types of single-tube landscape tower with lower height, the resistance and economical efficiency of dual-circle tower are both better than streetlight tower. Tri-tube tower has better economical efficiency than single-tube splicing tower when the tower height and wind pressure are the same. The resistance redundancy of these two types of tower is similar. Angle-steel tower possesses the highest resistance redundancy among al the types in the drawing col ection. Meanwhile the construction area of angle-steel tower is the largest. Hence angle-steel tower is suitable for the site with spare area or high wind pressure.
