建筑物沉降观测(国外英文资料) The observation data should be collected in time to calculate the settlement of observation points, the difference of settlement and the average settlement and settlement rate of this period. If the change in quantity is abnormal, the client shall be notified immediately to provide the basis for the measures to be taken and the observed frequency shall be increased appropriately. The observation of different periods shall follow the principle of five definite. The so-called five definite, which is the base point, base point and the settlement observation point of the observed observation, is stable. Stability of instruments and equipment; The observer should be stable; The environmental conditions of the observation are basically the same; The observation route, mirror position, procedure and method should be fixed. The above measures can ensure that the subjective uncertainty of observational error is minimized and the results of the measurement are unified. It is possible to ensure that the results of the multiple retests are consistent with the comparability of the first observations, making the observed settlement more realistic. In the 2222 s,,,,,, the precision of settlement observation demands the precision of settlement observation of settlement observation precision demands the precision of settlement observation According to the characteristics of building and construction, design unit level of requirements to the precision of settlement observation. In situations where no specific requirement, left general high-rise building structure construction process, the second-class leveling observation method can satisfy the requirement of settlement observation. The measurements of various observations are as follows: first, the difference between the round trip, the echo or the closed loop: delta h = sigma a minus sigma b is less than or equal to 1.0, and n stands for the number of stations; Second, its less than or equal to 30 meters. Third, th
