中-22級20m～40m上承钢鈑梁(大058)是专业院58年設計的。经过三年的制造使用,已经为我們进一步改进这项設計。提供了宝貴的资料。从各地区各部門的意见来看。原图在使用、养护、制造和材料以及设计等方面,都存在着不少的缺点。經研究后已作了修改和补充,修改后改为“专桥001”俟鑑定批后再将原图大058作废。主要的修改有: 1.根据养护部門反映 40m 跨度上承鈑梁,列車经过时横向摇摆震动较大。经过分析我們认为这种情况主要是原計算中假
In -22 20m ~ 40m on the steel sheet Beam (058) is a 58-year professional hospital design. After three years of manufacturing, this design has been further improved for us. Provided valuable information From the views of various departments and regions in all regions. The original image in the use, conservation, manufacturing and materials and design, there are many shortcomings. After the study has been made to modify and supplement, after the amendment changed to “special bridge 001” 俟 identification of large batch after the original 058 void. The main changes are: 1. According to the maintenance department to reflect the beam on the 40m span beam, the traversing lateral swing greater vibration. After analysis, we think this situation is mainly the original calculation of leave
