摘　　要：针对在基坑水平位移监测中,为避免基坑变形和施工等因素对监测基准点的影响而降低观测精度,提出了利用自由设站法进行观测,最小二乘法求坐标变换参数并解算监测点的水平位移的方法。经验证,该方法能保证观测精度,提高作业效率,在基坑工程中具有应用价值。In view of the foundation pit horizontal displacement monitoring,in order to avoid deformation and the construction of monitoring datum and reduce the influence of observation accuracy,put forward the liberal station method,least squares method for coordinate transformation parameters and calculating the horizontal displacement of monitoring points of the method.Verified that the method can ensure the observation accuracy,improve work efficiency,in the foundation pit engineering has application value.
