| 摘 要： | 采用一种新的三角高程测量方法进行变形监测,该方法可以使全站仪在任意点设站,减少了工作量,在测量中,不用量取仪器高、棱镜高,减少了三角高程测量中的误差来源,提高了精度。通过分析三角高程测量的精度,验证了精密三角高程测量代替几何水准测量的可行性与可靠性,结合基坑监测实例,将三角高程测量的数据与几何水准测量的数据进行比较,比较的结果显示,该三角测量方法结合精密全站仪可以替代几何水准测量,在实际工作中具有一定的适用性和参考价值。

| Abstract: | The paper introduces a new way of trigonometric leveling method for deformation monitoring.It features measuring with any setting station without measuring the height of instrument and prism,which reduces the sources of error and the field workload,improving accuracy.Analysis of trigonometric leveling precision monitoring,the monitoring of trigonometric elevation measurement precision and feasibility of its alternative geometrical leveling and reliability are discussed.Combined with the practice of foundation pit monitoring,the paper compares the triangle elevation survey data and geometric leveling data and the result shows that the triangulation method combined with the precision of total station can replace the geometric one.The above mentioned way of measuring can be applied to some cases and offers certain reference. |
