摘　　要：本文以顶管项目为依托，介绍了大直径长距离曲线顶管综合技术在软硬土层中的应用情况。重点阐述了刀盘改造、曲线测量、软硬地层顶进控制以及长距离注浆减阻和中继接力技术，这项综合技术在今后地下空间发展利用过程中将有很大的发展前景。本文可为以后类似工程建设提供借鉴和技术支持。Based on the pipe jacking project, the paper introduces the application of comprehensive technology of large diameter and long distance curved pipe jacking in soft soil and rock. The paper focuses on the transformation of the cutter head and the curve measurement and the top control of the soft and hard formation, as well as the technology of reducing resistance by slurry and relay jacks in long distance pipe jacking. This comprehensive technology will have great prospects for development and utilization of underground space in the future. It can provide reference and technical support for the construction of similar projects in the future.
