地面变形监测在防治地面塌陷、地面沉降和地裂缝等危害中有着极其重要的地位。本文采用气囊法对地面变形的发育过程展开了分布式光纤监测模型试验研究，详细介绍了分布式光纤监测的技术原理和试验方案，并对不同工况条件下分布式光纤监测结果进行了对比研究。研究结果表明：分布式光纤监测技术能够有效地捕捉不同条件下土体的变形情况，其“马鞍型”应变分布曲线能够清晰地定位底部拱形的形成区域以及地面变形可能发育的位置，该技术可应用于地面变形发育过程中土体的变形监测。

Soil deformation monitoring plays an important role in damage prevention of land deformation.In this paper,distributed monitoring model tests using airbag method are carried out to study the development of land deformation.The technical principles and test program of distributed fiber optic monitoring are introduced and the monitoring results under different conditions are analyzed.These results indicate that the distributed optical fiber monitoring technology can be effectively used to the deformation monitoring of soil under different conditions.The formation of arched area and land deformation can be located by the“saddle type”strain distribution curve.This technology can be applied to monitor the soil deformation during the development of land deformation.
