32m T梁桥梁墩高对工程经济延米指标的影响

32m简支T梁是铁路桥梁的传统梁型,设计简支T梁时考虑到新规范在纵向线性刚度和横向刚度方面的要求,对其进行技术经济分析,对设计的不同墩高的数量进行统计,对其基础和墩台所用材料的消耗指标进行比较,判断他们之间存在的递增关系。为便于统计分析,将引桥区段的墩高按一定范围划分,分析寻求其规律性,结果是随着墩高的增减其延米指标也...

Effects of 32m T Beam Bridge Pier Height to Project Economic Yanmi Index

32 m simply supported T beam is the traditional beam model of railway bridge.When the simply supported T beam is designed,we should take into account the new standard＇s requirements in longitudinal and transverse stiffness linear rigidity,analyze its technology economic,make number statistics of designed different pier height,compare the foundation and the materials consumption of pile caps,and judge the increasing relationship between them.For convenience of statistical analysis,the pier height is divided by certain section range.Its regularity is analyzed,whose result is that Yanmi index are different as high increase or reduce the pier height.
