In the process of tunnel excavation, in order to ensure the construction quality, the shield method is often used. In the shield construction, it is necessary to timely adjust and improve the status of the muck according to the actual construction progress so as to achieve the stable development of the construction process and ensure construction safety. However, for complex formation, the construction unit needs to analyze and fully understand the characteristics of the muck according to the geological conditions at the construction site, and select the best muck improver to ensure the actual improvement effect. Therefore, this article discusses the muck improvement in shield tunnel construction in complex formation, to provide a visual reference for tunnel construction.%在进行隧道开挖过程中,为了保证施工质量,经常使用盾构法,盾构施工中需要根据实际的施工进度,对渣土状态进行及时调整和改良,从而实现施工过程的稳定发展,保证施工安全.但是针对复杂地层,施工单位需要根据施工现场的地质情况,分析并充分的了解渣土特点,选择最佳的渣土改良剂,保证实际改良的效果.因此,本文针对复杂地层中盾构施工中渣土改良技术展开论述,为隧道工程建设提供可视化的参考依据.
