摘要:
收敛位移是隧洞开挖过程中围岩变形与应力状态变化最直观的反映之一。为克服传统自动化收敛监测仪器精度不高、自动化程度偏低、数据处理复杂、耐久性较差等缺点,构建了新型接触式隧洞收敛监测系统(TPMS)。通过求取最优监测平面的优化目标函数,将测点空间三维坐标换算为监测平面二维坐标,并推导了围岩收敛位移计算公式。基于高放废物地质处置“北山坑探设施”工程,使用TPMS对断层破碎带围岩进行了长期收敛位移监测试验,获得了监测断面位移包络图和各测点位移时程曲线,并与人工监测数据对比分析,论证了其使用的可行性和监测数据的准确性。试验数据表明:各测点位移大致随时间先呈线性增长后增长速率逐渐减小; 位移量自起拱处向拱顶逐渐增大,最大位移为1.174 mm,最大位移速率为0.007 98 mm/d。研究成果可为地下工程围岩收敛监测和分析提供借鉴与参考。
Abstract:
The convergence displacement is one of the most direct reflection of surrounding rock deformation and stress state changes during tunnel excavation.In order to overcome the defect of traditional automatic convergence monitoring instrument,such as poor precision,low automation,complex data processing,inferior durability and so on,the new type of contact tunnel profile monitoring system(TPMS)was constructed.To obtain the optimal objective function of the optimal monitoring plane,the 3D coordinate of the measuring point space was transformed into the two-dimensional coordinate of the monitoring plane,and the formula for calculating the displacement of the surrounding rock was derived.Based on the project of Beishan exploration tunnel for geological disposal of high-level radioactive waste,the long-term convergence displacement monitoring experiments of fractured zone surrounding rock were carried out by using TPMS.The displacement envelope of monitoring section and the displacement time history curves of monitoring points were obtained.By comparing with the manual monitoring data,the feasibility of its application and the accuracy of monitoring data were demonstrated.The experimental data showed that the displacement of each measuring point increased linearly with time on the whole,and then the growth rate decreased.The displacement increased from the arch to the vault,and the maximum displacement was 1.174 mm and the maximum displacement rate was 0.007 98 mm/d.The results could provide references for monitoring and analysis of surrounding rock convergence in underground engineering.
