1 工程概况小浪底南岸引水口工程是小浪底水利枢纽的组成部分,是为小浪底南岸灌区和洛阳市城市供水的大Ⅱ型引水工程。工作桥按汽-15设计,两跨,桥面宽6.4m,桥长50m。车辆核载为汽-20,挂车-100。按设计要求预应力钢丝采用碳素钢丝,技术条件必须符合《预应力结构用碳素钢丝》YB255-64的规定,单丝直径5mm,抗拉极限强度1569.60MPa,每束24丝。梁体结构形式为“T”型,设计为6孔道,编号为N_1、N_2、N_3、N_4、N_5、N_6,示意图如下:
1 Project Overview Xiaolangdi South Bank water intake project is an integral part of Xiaolangdi Water Control Project, for the Xiaolangdi South Bank Irrigation District and the city of Luoyang City, large Ⅱ water diversion project. Work Bridge by steam -15 design, two spans, the bridge width of 6.4m, 50m long bridge. Vehicle nuclear load as steam -20, trailer -100. According to the design requirements of prestressed steel wire with carbon steel, technical conditions must be consistent with “prestressed carbon steel wire” YB255-64 provisions of single wire diameter of 5mm, tensile ultimate strength of 1569.60MPa, 24 strands per bundle. The structure of the beam body is of “T” type, designed as a 6-hole tunnel, numbered as N_1, N_2, N_3, N_4, N_5, N_6. The schematic diagram is as follows:
