南京九华山隧道工程,在城市中建设,周边环境要求高,穿越明代古城墙施工段面临如何确保古城墙安全的问题,是施工的难点之一。通过计算分析确定隧道开挖爆破震动对明古城墙的影响范围,详细介绍了控制围岩沉降、控制爆破振动效应等确保古城墙安全所采用的技术措施;通过所进行的监测工作,证明了所采用技术措施的有效性。对城市隧道工程建设中的环境保护问题具有重要的应用价值。
Nanjing Jiuhuashan tunnel project, built in the city, the surrounding environment requires high through the Ming Dynasty ancient city wall construction section facing how to ensure the safety of the ancient city walls, is one of the difficulties of construction. Through the calculation and analysis to determine the impact of tunnel excavation blasting vibration on the ancient city wall, the paper introduces in detail the technical measures used to control the safety of the ancient city wall, such as controlling the settlement of surrounding rock and controlling the blasting vibration effect. Through the monitoring work, The effectiveness of using technical measures. It has important application value to the environmental protection in the urban tunnel construction.
