旧桥计算模型建模的讨论

The modeling discussion of the old bridge calculation model

分析了各种影响旧桥计算模拟建模精度的因素以及各种影响因素的影响情况,并通过对一个工程实例进行分析,对比了各种影响因素对计算模型影响的程度,并根据该工程的实际条件改变该桥的设计参数,并将理论结果与实际试验结果进行对比,吻合程度较好,说明了该方法的合理性和可行性。最后总结了对常见旧桥进行计算模拟的方式方法。

This paper analyzes the various factors which will affect the modeling accuracy of the old bridge. Through an engineering project analysis, it compares the degree of influence of various factors on the calculation model. by fixing the parameters based on the actual conditions of the project, it compares the theoretical results with the experimental results. The theoretical results are consistent with the actual test results. It shows the rationality and feasibility of the method. At last, it summarizes the method for the existing old bridge calculation model.
