摘要
在目前通常采用的桥梁静荷载试验中,试验规范推荐的分级加载法不能确保在分级加载过程中桥梁结构的多个控制截面同时是安全的。介绍安全加载域的定义、原理及计算过程,并优化加载过程的计算,将所有加载车的加载位置比拟成一个广义的点,使得安全动态加载的问题转化成求解安全加载域边界的几何问题,易于计算出安全加载路径。
At present,it usually uses the bridge static load experiment,the experimental standard recommendation＇s graduation load method cannot guarantee that in the graduation load process bridge structure＇s many control section simultaneously is safe.Introduced that the safe load territory the definition,the principle and computational process,and optimizes the load process the computation,will possess the load vehicle＇s load position to compare a generalized spot,causes the safe dynamic load the question to transform the solution safe load territory boundary the geometry question,easy to calculate the safe load way.
