摘　　要：随着中国经济的飞速发展,交通运输铁路也越来越多,高压线及临近高路堤铁路下施工工程难度不言而喻。66kV高压线下底净空临近既有高路堤铁路营运线桩基施工技术备受关注,以新建铁路用特大桥40#墩及41#墩临近既有高路堤运营铁路和66kV高压线双重不利因素下的桩基工程为背景,对高压线及临近高路堤铁路下钻孔灌注桩施工进行了风险分析,并从施工技术措施、现场管控、应急预案三个方面对施工安全防护进行深入的论述,取得了较好的社会经济效益。With the rapid development of China’s economy,there are more and more traffic and transportation railways,and the difficulty of high voltage line and near high road railway embankment is self-evident.The construction technology of pile foundation for the 66kV high-voltage line under the bottom clearance near the existing high embankment railway operation line has attracted much attention.Taking the pile foundation engineering of the newly-built railway super large bridge piers 40#and 41#near the existing high embankment operation railway and 66kV high-voltage line as the background,a risk analysis was conducted on the construction of bored piles under the high-voltage line and adjacent high embankment railway.In depth discussions were made on construction safety protection from three aspects:construction technical measures,on-site control,and emergency plans,achieving good social and economic benefits.
