1、毕业设计(论文)浅析精密水准测量在工程变形监测中的应用学生姓名系(部)勘测工程系专业工程测量指导教师2012年5月1日摘要工程变形监测的内容主要包括对各工程变形体进行的水平位移,垂直位移的监测。对变形体进行偏移、倾斜、绕度、弯曲、扭转、裂缝等的测量,主要是指对所描述的变形体自身形变和位移的几何测量的监测。采用工程变形的几何分在对精密水准测量的基础上,阐述了该项技术在变形监测中应用前景和地位。在普通水准测量原理基础上,做出了更高精度的要求和严密施测程序。如:往测奇数站采用观测后尺基本分划前尺基本分划前尺辅助分划后尺辅助分划,往测偶数站采用观测前尺基本分划后尺
2、基本分划后尺辅助分划前尺辅助分划。返测奇偶数测站的观测程序与往测偶奇数测站的程序相同。视线长度一般在50m以内,前后视距差小于1m,测段累计差小于3m,视距读至1mm,基辅差读至0.1mm,基辅高差之差小于0.6mm。实践证明,此项程序和精度要求完全符合变形监测应用。析和变形的物理解释的方法有效确定了变形要素的变形过程,以预测其变形的趋势和将会带来的影响,从而使得能够高效安全施工运营。关键词:水准测量变形监测数据分析精密测量31目录前言·····························································
