| 摘 要： | 煤矿开采通常会导致铁塔基础发生沉降,塔体受力发生改变,对铁塔基础的沉降和铁塔的受力情况进行了监测.对铁塔受力的监测采用应变计与配套测试仪,并给出了应变计和沉降监测点的布设方案.监测结果表明:铁塔基础与地表的沉降都不大,铁塔的应力变化也不大.这说明隧道采用三台阶式开挖,对此铁塔的影响较小,可以保证铁塔的安全. |
| 关 键 词： | 隧道开挖 铁塔 应变计 应力 沉降 |

| Abstract: | Coal mining often results in settlement of tower foundation and stress change of tower.The settlement of tower foundation and stress of tower are monitored.The strain gauge and matching tester is used to monitor the stress of tower.The layout plan of strain gauges and settlement monitoring points are introduced.The monitoring results show that the settlements of tower foundation and ground surface as well as the stress changes of tower are small.It shows that the impact of three-step tunnel excavation on to... |
