基坑工程对下穿运营铁路立交的影响与保护

摘要:

摘要：交通基础建设的作用随城市发展愈加明显，本文结合苏州城北路改建工程下穿京沪铁路、沪宁高铁立交节点工程，分析基坑工程对下穿运营铁路立交的影响及建议措施，并着重从设计、施工、监测等方面探讨基坑施工期间为确保铁路立交运营安全采取的各项保护措施。通过对施工过程和监测数据的分析，认为采取的基坑围护方案、铁路慢行等各项保护措施的必要性及可实施性，并通过监测数据实时指导基坑工程施工，确保京沪铁路、沪宁高铁的安全运营，可为后续同类工程建设提供借鉴。

Abstract：The role of traffic infrastructure construction is becoming more and more obvious with the development of the city. In this paper, combined with the reconstruction project of Suzhou North Railway underpassing the Beijing-Shanghai railway and the Shanghai-Nanjing high-speed railway interchange node project, the influence of foundation pit engineering on the underpassing operation of railway interchange and the recommended measures are analyzed, and the protection measures adopted to ensure the safety of railway interchange operation during the construction of foundation pit are emphatically discussed from the aspects of design, construction and monitoring. Through the analysis of the construction process and monitoring data, it is considered that the necessity and feasibility of various protection measures such as foundation pit support scheme and railway slow operation are taken, and the monitoring data are used to guide the construction of foundation pit in real time to ensure the safe operation of Beijing-Shanghai railway and Shanghai-Nanjing high-speed railway, which can provide reference for the subsequent similar projects.
