摘　　要：针对TRD的工法特点,以南京地铁七号线莫愁湖站施工为例,建立了在富水砂层中TRD施工时间、施工效率、墙体垂直度、水泥土强度等施工参数,以及质量控制等方面的施工质量控制方法。实践表明,本文建立的基于现场监测的TRD施工质量控制方法,可减少施工风险,确保安全、高效、优质地完成TRD施工。According to the characteristics of the TRD construction method,taking the construction of Mochouhu Station of Nanjing Metro Line 7 as an example,the construction parameters such as the TRD construction time,construction efficiency,wall verticality,cement-soil strength,etc.and the construction quality control method in the water-rich sand layer have been established.The practice has shown that the TRD construction quality control method based on field monitoring established in this paper can reduce construction risks and ensure safe,efficient and high-quality completion of TRD construction.
