DiNi12数字水准仪进行基坑监测的技术指标探讨及应用

The application and discussion on indicators of DiNi12 digital leveling for foundation pit monitoring

通过对DiNi12数字水准仪进行精度测试实验,得出影响数字水准测量精度的主要因素。针对现行规范的疏漏,探讨应用DiNi12数字水准仪进行二等垂直位移监测的测站精度技术指标,结合南京市某深基坑的沉降位移监测工程实例,证明其可行性。

Through the precision test experiments by DiNi12 digital levels, the main factors of digital level- ing precision is derived. Aiming at the existing specifications, it discussed stations precision technical indicators for the application of the second the vertical displacement monitoring by DiNi12 digital levels, combined with the settlement of a deep foundation pit in Nanjing Displacement Monitoring Project. Examples prove its feasibility.
