摘要
随着城市轨道交通的高速发展,盾构法以其环保、安全、快速、影响小等优势在城市轨道交通建设过程中被广泛使用。洛阳地铁项目位于洛河一级阶地,局部隧道位于富水砂卵石地层中,在富水砂卵石地层的施工过程中遇到地下水位高,地层含水量丰富以及稳定性差等问题。由此本文通过对洛阳地铁某区间两台盾构施工实践进行分析,从而探索盾构施工新技术,为类似工程提供借鉴。
With the rapid development of urban rail transit,shield tunneling has been widely used in the construction of urban rail transit with its advantages of environmental protection,safety,speed,and low impact.The Luoyang Metro Project is located on the first terrace of Luohe River.Some tunnels are located in the water-rich sand and pebble stratum.During the construction of the water-rich sand and pebble stratum,problems such as high groundwater level,rich stratum water content and poor stability were encountered.Therefore,this article analyzes the construction practice of two shields in a certain section of Luoyang Metro,so as to explore new shield construction techniques and provide reference for similar projects.
