中文摘要：
通过京沪高铁昆山东桥施工及箱梁架设期间墩身沉降观测,分析了深厚软土地区高速铁路桥梁工后沉降规律.得出墩顶荷载和基础沉降量的最大值发生在架梁作业时,架梁结束后基础沉降有小幅反弹,架梁后3个月内基础沉降均已收敛达到无砟轨道铺设条件.采用修正的等代墩基法理论计算方法对深厚软土地区桥梁沉降进行计算,并分析计算值和实测值存在差异的原因,得出土体压缩模量、施工工艺及观测时间对基础沉降有较大影响等结论.
英文摘要：
In this paper, the general rule of the high-speed railway bridge settlement after construction was analyzed through field measurements in deep soft soil area on Beijing--Shanghai high-speed rail- way Kunshan eastern bridge. And some conclusions were drawn. The maximum of the load on the pier and the settlement of the bridge appear when the beam is erecting. The settlement of cap slightly
