| 摘 要： | 桥涵顶进施工中常出现抬头、扎头或方向偏差等问题,对此除应加强观测、认真预防外,还必须及时纠偏。运用大型有限元软件ANSYS计算某大型斜交框架式地道桥顶进纠偏施工时桥体产生的剪应力和主拉应力,并依此应力作为施工顶进纠偏的控制参数之一,对该地道桥体结构尺寸进行优化设计。

| Abstract: | Problems such as head rising, head firming or deviated direction often occur during bridge and culvert construction with jacking method. Rectification should be taken in time in addition to observation, survey and the precautionary measures. By using the finite element software (ANSYS) , the shear stress and main tensile stress are calculated occurred during construction of a large - scale obliquely intersected framed underpass bridge. And then taking the value of the stress as one of the control parameters , the structural dimension of the underpass bridge is designed optimally. |
