| 摘 要： | 针对目前小净距空间交叉隧道开挖扰动大而容易导致既有隧道受到影响的问题，相关实例分析发现，在隧道施工中应对底板较薄弱的地段采用人工辅以机械开挖，同时在爆破作业中应遵循短进尺、弱爆破的原则，参考爆破震动监控量测反馈信息，及时调整爆破方案，以达到控制其对既有建构筑物的影响的目的。

| Abstract: | Currently digging cross tunnel with small interval is inclined to causing some distrubance and bringing negative influence on the existing tunnels. In view of this, related projects indicates that the manual way by dint of equipment should be taken for the thinner soleplate during the tunnel construction, at the same time should follow the rule of short footage, weak blasting in blast excavating. Meanwhile the feedback information of blast vibration monitor should be referred so as to adjust the blast scheme in time to carry out the point of reducing the negative impact on the existing building. |
