Variational sloping angle of arch rib influenced on the stability of double X-shaped arch bridge tilting position 斜靠式拱桥拱肋倾角变化对稳定性能的影响倾斜角(转炉),倾斜位置
Tbe different straightening methods with flame heating for side bending, hogging, angle distortion of rib plate, local unevenness of web and torsion of whole crane beam are introduced in the paper. 介绍了对焊接引起的吊车梁旁弯、拱度、翼板角变形及腹板局部不平直度以及吊车梁整体扭曲等变形所采用的不同火焰矫形工艺。
The running load of AFC in a fully mechanized face changes with such factors as, dip angle and thickness of coal seam, length of face, spalling of rib, especially haulage speed and position of shearer at face in coal cutting. 综采面输送机的运行负荷是随着煤层倾角、煤层厚度、工作面长度、煤壁片帮情况、特别是采煤机割煤时的牵引速度以及采煤机在工作面的工作位置的不同而变化。
Study on the stability influence of the angle of toe-in of the arch rib 提篮式拱桥拱肋内倾角对横向稳定性的影响
The inclination angle of arch rib and the height of concrete-spouting at the arch springing are two important parameters in the design of Steel tube& Con-crete-filled steel tube X arch bridge, they greatly influence the performance of the structure in stable properties and dynamic characteristics. 拱肋内倾角和拱脚混凝土灌注高度是钢管-钢管混凝土提篮拱设计中的两个重要参数,他们对于成桥结构的内力、稳定和动力特性都有很大的影响。
