| 摘 要： | 地铁隧道施工过程遇到险情时,参建各方须迅速做出应急响应,其中应急监测结果对险情诱因判断及排险方案的制定起关键性作用。为解决紧急情况下无法布设稳定变形监测基准点的难题,结合应急监测实例,提出以边墙点的重心作为沉降监测基准,以非接触式解析法进行净空收敛监测的应急监测解决方案。实践证明方案具备操作简便、精度可靠的特点,满足应急监测需求,其成果有助于险情诱因的判断,对应急排险方案的制定具有一定参考价值。

| Abstract: | It is very important to make quick emergency response when the danger occurs during subway tunnel construction,among which the emergency monitoring plays a key role in determining the incentives of risk and formulating the risk program. To solve the problem in emergency situations that cannot be set a stable deformation monitoring reference point, combining the emergency monitoring instance, it presents an emergency monitoring solution that uses the center of gravity as subsidence monitoring benchmark and non-contact analytical method as the clearance convergence monitoring. Engineering practice has proved that the program has a simple, precision reliable characteristic, and meets the needs of emergency monitoring. Monitoring results contribute to judging the incentives of danger and formulating the emergency insurance program. |
