摘要

高速铁路桥梁沉降控制是保证施工质量的重要措施。通过对京沪高速铁路桥梁大量沉降观测资料的积累，对软土地基沉降过程具有一定实际应用价值的沉降变形规律进行曲线回归，以预测其沉降发展规律。为了对桥梁基础沉降曲线全过程进行拟合和预测，通过各种理论计算和大量沉降观测资料的分析、统计归纳，首次提出了变形过程指数法。该成果为适用于京沪高速铁路及其他相关工程的桥涵基础的沉降预测提拱参考依据

Abstract

High-speed railway bridge settlement conformity is a major measure to ensure the high-speed railway construction quality. Through accumulating the observed data of settlements of a large number of high-speed railway bridges

and then analyzing the process of settlements of soft soil by using curve fitting the settlement deformation laws which is practical application value

the development of settlement law can be predicted. In order to predict the whole process of bridge base settlements and make carve fitting

through a variety of theoretical calculations and a large amount of the settlement analysis of observed data statistical induction

the following index of the deformation process method is proposed first. The results have been applied to the Beijing-Shanghai High-speed Railway and other related projects to predict their foundations’ settlements
