prestressed concrete girder bridge

基本解釋

Based on the practical engineering, discussion is made on the design and evaluation of moulding board brace for one prestressed concrete continuous girder bridge.
結(jié)合具體工程實(shí)例，介紹了某預(yù)應(yīng)力混凝土連續(xù)梁橋的模板與支架設(shè)計(jì)方案及設(shè)計(jì)計(jì)算。
The calculation results and investigations show that overlarge local tension stress is supposed to be the main reason of slab cracks in prestressed concrete continuous girder bridge.
計(jì)算結(jié)果和現(xiàn)場(chǎng)觀察情況表明，腹板處局部主拉應(yīng)力過(guò)大是預(yù)應(yīng)力混凝土連續(xù)箱梁橋在施工過(guò)程中出現(xiàn)腹板斜裂縫的主要原因。
When using reinforced-stress gauge to measure structural stresses in prestressed concrete girder bridge, there exist errors between measured values and the theoretical ones because of various factors.
采用鋼弦式應(yīng)力計(jì)測(cè)量預(yù)應(yīng)力混凝土橋梁結(jié)構(gòu)應(yīng)力時(shí)，由于種種原因，將導(dǎo)致測(cè)試結(jié)果與理論計(jì)算結(jié)果不符。
