摘要
针对复杂条件下高地应力煤系软岩地层隧道大变形和施工难点,采用理论分析、数值模拟和现场实验等多种手段进行了综合研究,形成了对高地应力煤系软岩地层隧道围岩大变形合理控制施工和支护的关键技术,工程试验和实践表明,该方案取得了有效控制围岩大变形的良好效果.
For the difficult problems and large deformation of tunneling in the weak rocks of coal measures strata under complex high ground stress,various methods,such as the theoretical analysis,numerical simulation and we field experiment were used to conduct the comprehensive research,and we formed a key technology of controlling the deformation by effective operation and support measures.The practice and experiments showed that a good result of control the large deformation had been made by using the key technology.
