某大厦深基坑开挖与施工安全监测实践与体会

The Practice and Preception of Safe Monitoring in Some Deep Foundation Ditch Excavation and Construct

从深基坑安全监测实例出发,介绍了一种简便、易行、稳定、可靠的射线形水平位移基准网,同时适用用小角法高精度位移监测。另外就温度的变化对水平位移值的影响,降水施工对地面沉降,深层土体位移的影响及测斜管埋设的重要性提出了自己的观点、认识与体会,希望对类似工程有一定参考价值。

Based on the example of safe monitoring of a deep foundation ditch, This paper introduces a simple, convenient and reliable radial shape horizontal displacement reference network. It fit to high-precislon displacement monitoring by minor angle method. The author put forward to his opinion understand and experience to the effect of thermometer changes on horizontal displacement, the effect of precipitation on subsidence and deep dust displacement, the significance of clinometer. Management, there are some reference value on analogy project.
