隧道爆破施工对邻边古迹的影响与控制措施研究

Study on Influence and Control Measures of Tunnel Blasting Construction on Adjacent Monuments

摘要:

在高等级公路建设过程中，因各种因素的制约，往往存在着选线无法避免的隧道经过文化遗迹的情况。为解决隧道爆破施工对临边古迹及建（构）筑物的影响问题，以西北地区某改扩建工程越岭隧道为研究背景，利用爆破振动监测手段来评估隧道爆破产生地震波的强度，并根据监测数据反馈动态调整优化爆破方案；同时对危岩与石刻古迹进行专项加固与防护，并考虑在古庙周边加装保护层，起到双重保险的作用。研究表明，控制措施实施效果良好，成功避免了隧道爆破施工对临边古迹与古建筑物的不利影响。

Abstract:

In the construction process of high-grade highways, due to the constraints of various factors, there are often some unavoidable situations where the tunnel passes through the cultural relics during the route selection. In order to solve the influence of tunnel blasting construction on the adjacent monuments and buildings （structures), taking the crossing-ridge tunnel of a reconstruction and expansion project in Northwest China as the research background, the blasting vibration monitoring method is used to evaluate the intensity of seismic waves generated by tunnel blasting， and the blasting scheme is dynamically adjusted and optimized according to the feedback of monitoring data. At the same time, the special reinforcement and protection of dangerous rocks and stone monuments are carried out. And a protective layer is considered to be installed around the ancient temple to play a double insurance role. The results show that the effect of the control measures is good, and the adverse effects of tunnel blasting construction on adjacent monuments and ancient buildings are avoided successfully.
