- Abstract:
- Taking the Baishuiyu bridge as the back ground，using the finite element software MIDAS／Civil to buih the space beam finite element modelof five span continuous rigid frame bridge，horizontaldisplacement of the finished bridge’s main girder is analyzed under differentjackingforce，then effect among the closure’s temperature．jacking forceand horizontal displacement is discussed．Through numerical calculation and con‘ trast。it drawsthe conclusion that the relationbetweenjackingforceand horizontal displacement are linearvar。iation．The effect of iacking force of the side middle span and middle span to pier top’s horizontal displace。ment is different．When iackingforce of sidemiddle span is increased，it is favorable to the side span’s main pier of the horizontal displacement and unfavorable to the middle span’s main pier of the horizontal displace。ment．When iackingforce of middle span is increased，it is favorable to all main pier of the horizontal dis。Dlacement．So to the five span continuous rigid frame bridge，it should preferentially adjust jacking force of main span．Finally．according to temperature of the fact site，to use relation between closure’s temperature andhorizontal displacement，jacking force is adjusted to optimize thejacking force．
