摘要
在铁路桥梁深埋承台工程中,深基坑是重要的施工环节,对铁路桥梁工程的整体稳定性有着重要影响。昌景黄铁路线工程中有2个5 m以上的深基坑,以其中51#深基坑承台为案例,采用拉森钢板桩作为深基坑支护结构,配合四周设置排水沟和集水井避免地下水及地表水的影响,以及实时的基坑变形监测,确保深基坑施工质量。结果显示,采取上述施工后,深基坑工程能如期完成施工,施工期间未出现安全事故,验收质量合格,取得理想的施工效果。
The deep foundation pit is an important construction link in the deep-buried bearing platform engineering of railway bridges,which has an important influence on the overall stability of the railway bridge engineering.There are 2 deep foundation pits over 5m in the Nanchang-Jingdezhen-Huangshan Railway Line.Based on the 51#deep foundation pit platform,Larsen steel sheet piles are used as the supporting structure of the deep foundation pit,and drainage ditches and water collection wells are set around to avoid the influence of groundwater and surface water,and real-time foundation pit deformation monitoring is adopted to ensure the construction quality.The results show that the deep foundation pit project can be completed as scheduled due to the above measures with qualified ideal construction effect,without any safety accident during the constructing.
