摘要
静载试验是对公路桥梁承载能力进行评定的最直接有效的手段,但对于梁体下部空间有限或受其他条件限制时,无法顺利地完成应变片布置等下部工作的,就不得不考虑只在桥梁的上部利用挠度来完成试验。本文结合工程实例与ANSYS有限元模型,来分析基于挠度的公路桥梁静载试验的可靠性。
The most direct and effective means to assess the carrying capacity of highway bridges is the static load test. But the space under the beam is limited or restricted by some conditions some times,we can't accomplish strain gauge and other workings successfully,so the deflection in the upper part of the bridge had to be taken into account to finish the test. This essay combines engineering example with ANSYS finite element model,to analyze the reliability of highway bridge static test based on deflection.
