| 摘 要： | 梁格法是一种能较好地模拟原结构的空间结构分析方法,它能得到主要控制断面的弯矩、挠度、应变数据,以满足梁桥荷载试验理论计算要求。以装配式小箱梁桥猫儿洞大桥为研究对象,利用Midas/civil分别建立梁格模型和单梁模型,通过对比分析试验结果判定梁格法在装配式小箱梁桥荷载试验中的可行性、实用性和准确性,对梁格理论的理解及其在装配式小箱梁桥荷载试验中的应用提供借鉴参考。

| Abstract: | The grillage method is an analytical method of space structure which can provide some data about static deflection and strain of the primary control section,to satisfy the box-girder bridge static test requirements of theoretical calculations.Take the Mao erdong Bridge for study,the use of Midas/civil establishment of bridge girder model and single-girder model.Through the comparison and analysis of the test result to determine grillage method in the load test of Fabricated small box-girder bridge is feasib... |
