摘要
就某煤矿栈桥框架结构梁的破坏进行了深入分析,并针对其中可能产生破坏的两个主要因素建立起相应的力学模型,分别进行计算分析,求得各自可产生的作用。最后,通过进行比较,得出梁破坏的真正原因。从而为栈桥的修复提供了可靠的力学依据,并且可供类似工程参考。
The destruction reasons of the beams of a coalmine bridge framework were more deeply analyzed, and the corresponding mechanics models were established for two main factors that may produce destruction. Then each one was calculated and analyzed respectively to get the function that each factor may produce. Finally, the true reason of the destruction is got by comparison. Thereby the reliable mechanics basis of the bridge reconstruct can be provided and also can be the reference of some comparable engineering.
