Abstract: Cast-in-situ box girder mainly adopts full support， portal support， and steel tube columns in the construction In poor geological condition， especially in water condition， the exists problems such as difficult and comlex foundation treatment in full framing and door timbering， which prevent people from construction， so choosing steel tube columns is more To determine the actual working condition and the stress state of the support and evaluate whether the support can be put into use normally， the author will describe the static load experiment of the suppot steel column in (详细阐述支架钢管柱静载实验的全过程 这句话是结尾了吧，我看后面是个分号)key words: cast-in-situ， steel column support， static load experiment
本文翻译：Cast-in-situ box girder in construction process mainly adopts full framing， door timbering， steel tube column method such as construction， in the foundation of poor geological conditions， construction especially in construction of the water， full framing， door timbering existence foundation treatment， foundation construction problems such as complex can't， choose steel tube column method is more suitable; To determine the actual working condition and stress state of stents， evaluation of stents can be put into use normally， detail support steel tube column during the process of static load experiment
