Combined with the high pier construction of a continuous bridge,it simply introduces the main factors which affect the vertical degree of bridge pier,and introduces temperature s effects on vertical degree of continuous steel bridge pier,brings forward measures in reducing high and huge bridge pier s leaning in construction,so as to achieve the aim of controlling bridge pier s vertical degree.

Pipeline jam accidents appear frequently during pumping construction of concrete of high-pier and long-span bridge,which result in not only great economic loss,but also serious delay of project completion.

With the high and strong materials and the thin wall structure used widely, the stability problem of the beam bridges with high-piers and long-spans becomes more and more important.
