The flexual deformation of casing in a horizontal hole is caused not only by the uniform transverse load from dead weight, but also by the axial load, and the existence of initial bent if any.
Afterwards the influences of uneven distribution of the live load, different ratios of live load and deadload and initial shortage of structure to stability behaviors are studied. Finally;
然后，研究了活载不均匀分布、活载与恒载不同比值和结构不同的初始缺陷对结构稳定性能的影响程度。

Finally, the initial construction state and deadload state of Jiangyin Yangtze River Highway Bridge are calculated as a numerical example. It is shown that the initial construction sta...
