差异沉降法中倾斜量的正算与反演

Positive counting and in reverse of inclination volume in differential settlement

针对差异沉降法倾斜观测数据的处理,及与其他方法所得成果的比对需要等问题,本文理论推导了任意两方向沉降差正算监测体最大倾斜角、倾斜方向的可靠公式,并用算例验算其正确性;由于差异沉降法一般不能反映0期监测时的倾斜量,本文提出将当前倾斜量作基础沉降差反演,导出通式,求得"原始高程",使后期沉降差完整反映监测体倾斜状态成为可能;最后通过试验验证本文方法。

As to the observing data processing in differential settlement and comparing the various achievements, this paper theo- retically derives the dependable formula of calculating the angle and direction of inclination from the observer in two random ways and tests the accuracy of examples. As differential settlement cannot reflect the inclination data at the 0 time, the current inclination data is used for counting of differential settlement in reverse, deriving a general formula and obtaining ＂original height＂ . On the bases of them, it becomes possible that the late differential settlement entirely reflects the inclination of observer. The calculating approaches, which approve the differential settlement and provide a reference for the similar engeneering, are proved by examples at last.
