以郑州地铁1号线东明路站-民航路站区间隧道盾构穿越电缆隧道工程为背景,阐述了盾构在郑州砂性土地层中长距离穿越建(构)筑物的环境保护技术。通过数值模拟仿真、施工技术措施优化、施工监测数据反馈与分析等方法指导施工,保障了工程的顺利实施。 Taking the tunnel shield tunneling project of Dongming Road Station - Minhang Road Station of Zhengzhou Metro Line 1 as an example, this paper describes the environmental protection technology of long - distance crossing of the shield in Zhengzhou sandy soil layer. Through the numerical simulation, optimization of construction technology measures, construction monitoring data feedback and analysis and other methods to guide the construction, to ensure the smooth implementation of the project.
