摘要:

通过对某综合楼的沉降与倾斜观测实例,说明测小角法是一种观测高层建筑物倾斜变形的快速、有效方法 .该法对基准点的要求不高,选点灵活,在建筑物密集区,更具优越性 .同时,讨论变形观测精度与周期的确定办法 .在施工阶段,应以建筑物安全为目的,观测精度可取允许偏差量的1/ 10~ 1/ 2 0,而观测周期应根据荷载的变化确定 .当建筑物有危险迹象时,应采用高精度和短周期,以便尽快发现问题,采取必要措施,避免事故发生

Abstract:

As explained by a living example of observing settlement and inclination of a certain multi purpose building, sarveying small angle is a fast and effeetive method for observing inclination and deformation of a high rise building. The method is characterized by not demanding with a reference point and flexible in reconnaissance and preferable to a region with buildings densely located. A discussion is then devoted to the means of determining precision and period of observing the deformation. The safety of a building should be the goal during the stage of construction. An allowable depature of 1/10~1/20 may be taken as the precision of observation while the period of observation should be determined according to the change of load. In case an indication of danger appearing in a building, high precision and short period should be adopted for finding the problem as soon as possible and necessary measure should be taken for avoiding the occurrence of accident.
