Abstract

Deformation and subsidence measurements are very vital for stability of structures and buildings. Deformation and subsidence monitoring are easily carried out with the aid of established baselines. This study focuses on the establishment of baseline for monitoring deformation and subsidence within university of Lagos. Geodetic method of control establishment was adopted, where five (5) control stations were established on stable grounds across the university of Lagos main campus with Differential GPS observation carried out on them and data obtained were processed and analysed statistically. The result of the findings shows that the baseline established is very reliable, given that the vertical controls have their relative redundancy number rij ranging between 0.1

海岸环境变形和沉降监测基线的建立——以拉各斯大学为例

变形和沉降测量对结构和建筑物的稳定性至关重要。借助已建立的基线，便于进行变形和沉降监测。本研究的重点是拉各斯大学内部变形和沉降监测基线的建立。控制建立采用大地测量法，在拉各斯大学主校区的稳定地面上建立5个控制站，对其进行差分GPS观测，并对数据进行处理和统计分析。研究结果表明，考虑到垂直控制的相对冗余数rij在0.1
