%X 地铁区间隧道下穿运营铁路施工难度大&#65292;安全风险高&#65292;需采取合理的安全防护措施确保安全。本文以北京地铁19号线新宫站~新发地站区间隧道下穿运营铁路为背景&#65292;研究了地铁盾构区间下穿铁路加强注浆、深孔注浆、轨道结构加固及接触网改移等防护措施。工程实施监测结果表明&#65292;铁路安全防护措施合理、有效&#65292;施工期间铁路运营安全。<br>The construction of the subway tunnel under the operating railway is difficult and the safety risk is high. It is necessary to take reasonable safety protection measures to ensure safety. Based on the background of the tunnel between Xingong Station and Xinfadi Station of Beijing Metro Line 19 under passing the operating railway, this paper studies the protective measures such as strengthening grouting, deep hole grouting, track structure reinforcement and catenary change. The monitoring results of the project show that the railway safety protection measures are reasonable and effective, and the railway operation is safe during the construction period.
