摘要
高速铁路线下工程完成后的最终沉降量是合理确定轨道开始铺设时间、确保轨道结构铺设质量的关键因素,通过对哈大、沪杭、石武等高速铁路线下工程沉降资料的分析,总结出高速铁路线下工程沉降观测变形规律及特点,并据此开发了沉降观测评估软件,在高速铁路线下工程的工后沉降预测计算与分析中进行了实际应用与验证。其综合分析及评估成果为高速铁路铺轨施工提供依据。
The final post-construction settlement of high-speed railway foundation works is the key factor for determining the starting time of track laying and ensuring the laying quality.According to the analysis of the settlement data of Harbin-Dalian,Shanghai-Hangzhou and Shijiazhuang-Wuhan high-speed railways,we summarize the deformation laws of settlement observation for high-speed railway foundation works and develop the post-construction settlement prediction software.And it has been used in analysis and calculation of post-construction settlement prediction of high-speed railway foundation works,which provide references for track laying of high-speed railway construction.
