现行水电部部颁《架空送电线路设计技术规程》(SDJ3-79)第67条规定:“普通钢筋混凝土构件的设计强度安全系数不应小于1.7;预应力混凝土构件的设计强度安全系数不应小于1.8”.比之1959年部颁规程第62条规定的钢筋混凝土电杆结构的强度安全系数在正常荷重情况下为2.0,从表面数值看似乎降低了标准,有的单位曾表示耽心,但
The current Ministry of Water Resources and Development’s “Technical Specification for Design of Overhead Transmission Lines” (SDJ3-79) provides that: "The safety factor of the design strength of ordinary reinforced concrete members shall not be less than 1.7; the safety factor of the design strength of prestressed concrete members is not The strength safety factor of the reinforced concrete pole structure stipulated in Article 62 of the Ministerial Regulations of the Ministry of Justice of 1959 shall be less than 1.8%. It is 2.0 under normal load conditions. From the surface values, it seems to have lowered the standard. Some units have indicated that Heart, but
