摘要
针对澳门新瞭望台大楼基础的下沉,按Ⅱ等精密水准测量的各项要求用NI004精密水准仪及线条式铟瓦水准尺进行沉降观测,采用秩亏自由网平差方法进行计算,按求条件极值的方法,组成附有条件的间接平差的法方程式,改变了法方程组系数阵的奇异性。
In view of the settlement of the foundation of Macao New Lookout Tower,we monitored the settlement according toⅡgrade precision leveling requirements.Precise NI004 Levels and indium-watt standard leveling line rods were used,and rank defect free network adjustment method was adopted to calculate the settlement.The use of the conditional extremum seeking method to form the normal equation of a conditional indirect adjustment has made the singularity of the coefficient matrix of the normal equations changed.
