摘要
结合泰宁隧道的工程实践,通过拱顶沉降、围岩收敛、围岩压力和钢拱架内力的现场监控量测工作,研究复杂地质条件下上下台阶法施工时围岩的稳定性。研究的方法、分析过程和结论可为类似条件下隧道工程的设计、施工、监测和进一步的理论研究提供参考和借鉴。
The stability of surrounding rock was studied during the benching tunneling construction period under the complicated geological condition through the on-site monitoring of settlement of vault,convergence of surrounding rock,pressure of surrounding rock and internal force of steel arch based on Taining tunnel.The method,analysis and conclusion of research was as the reference in design,construction,monitoring and further theoretical research on tunnel engineering under similar condition.
