某大型厂房地面垂直形变监测

Ground Vertical Deformation Monitoring of Large Scale Factory Building

结合西北地区黄土塬上某大型厂房地面垂直形变的监测工作,提出和应用选定在具有代表性的监测区域布点、改进标尺进行观测等一系列行之有效的方法和措施,取得了满意的结果。通过监测数据分析,指出型架的不稳定主要是因为温度变化而导致地面不均匀垂直形变引起的,为厂房地面不均匀垂直形变的治理提供了依据。

Monitoring the ground vertical deformation of the large factory in a high precision is an important problem in precise engineering survey. By the work of monitoring the ground vertical deformation of a large factory in the northwest loess tableland, this paper puts forward and applies some effective methods and measures for example choosing the typi eal monitoring area to set up monitoring points, improving on staff guage and so on. At last satisfactory results are got ten. By analyzing the monitoring data, it points out that the leading reason of jig instability is the ground vertical deform- ation which is caused by temperature changing. This provides grounds for the harnessing of this factory. These methods and measures are of great reference value for design staff, builders and managers.
