盖梁的设计与计算

桥梁设计中,柱式桥墩是普遍采用的结构型式。对于简支桥梁,盖梁是一个承上启下的重要构件,上部结构的荷载通过盖梁传递给下部结构和基础,盖梁是主要的受力结构。在设计中,由于桥梁的跨径、斜度、桥宽、车辆荷载标准的变化,对盖梁设计的影响很大,很难完全套用标准图和通用图。盖梁设计的标准化程度很低,经常是非标准设计,需要对盖梁进行较多的计算,所以盖梁设计是桥梁设计的一个关键部分。

Design and Computing of Coping

Column pier is generally applied in bridge design.To simple beam bridge,coping is an important connecting link between superstructure and understructure.The load of superstructure is transferred to understructure through the coping,which is the primary component bearing force.The change of span,pitch,width of bridge and standard of vehicle load has great influence on coping design,which is hard to use normal map and standard drawing indiscriminately.The standardization degree of coping design is very low,even is nonstandard,therefore it is necessary to carry on much computing on coping.In a word,coping design is a key part of bridge design.
