建筑物建成后会引起基础及其四周的地层产生变形,这种变形在一定范围内是正常的,但超过某一限度,不仅会影响建筑物正常使用,严重时还会危及安全。_为了建筑物的安全使用,对其进行变形观测是一项不容忽视的工作。然而,在实际工作中,我们往往对观测等级及观测周期不进行严格设定,就身边软、硬件之条件顺势而为,或 After the building is completed, it will cause the deformation of the ground and the surrounding strata. Such deformation is normal within a certain range. However, exceeding a certain limit will not only affect the normal use of the building but also endanger the safety in serious cases. _ For the safe use of buildings, deformation observation is a work that can not be ignored. However, in practical work, we often do not strictly observe the observation grade and the observation period, and take the advantages of the hardware and software around us, or
