摘要

以汶川大地震中严重破坏的回澜立交桥为例

基于数值模拟手段并结合现场震害调查

分析了回澜立交桥的地震破坏机理。数值分析表明

地震时设有支座的最矮的1号桥墩支座发生滑移破坏

以致刚度较大（次矮）的2号刚构桥墩承受很大的地震惯性力

2号墩首先发生弯曲屈服

此后随延性发展因抗剪能力不足最终发生剪切破坏直至倒塌损毁

呈现典型的弯剪破坏特征。现场震害调查发现

回澜立交桥震害集中于抗弯刚度较大的刚构墩上

而其余桥墩震害相对较轻

主要表现为混凝土保护层的脱落、混凝土开裂以及墩顶支座的滑移破坏等。数值分析结果与震害调查呈现出较好的一致性。

Abstract

The seismic damage mechanism of Huilan interchange

which was severely damaged during Wenchuan earthquake

was studied through numerical simulation and post-earthquake investigation.The simulation results show that the bearing at the top of the most shortest No.1 pier was firstly damaged due to sliding.Then

seismic action concentrated on the next shortest No.2 rigid frame pier which has a larger stiffness.No.2 pier firstly yielded in flexure

and as the lateral displacement increased

the No.2 pier was dominated by shear capacity

and eventually failed in flexure-shear modes.By field investigation

it was found that the short rigid frame piers with largest lateral stiffness suffered severely damage while other piers suffered slight-to-moderate damage

which including concrete cover spalling

concrete cracking and sliding damage of the rubber bearing on the top of piers.It is concluded that the simulation results agree well with post-earthquake investigations.
