he spatial trend can be derived for one or two dimensional networks by considering the differences in coordinates estimated in the individual campaign adjustments, ., paring campaigns. Spatial trend can also be derived vertically for subsidence profiles.Finally the reporting of the deformation survey should include the history of the project as some projects could extend over a significant period of time. The report should also include the methodology containing results of the individual campaign (epoch), the geometrical displacements and the quality of the displacements, graphic depiction and remendations or conclusions.7 / 7。 spatial distance。Unit 19 Deformation Monitoring of Engineering Structure(工程建筑【Engineering Structure或者工程結(jié)構(gòu)】的變形觀測)Overview(概述【Overview縱覽、總的看法】)Deformation refers to the changes of a deformable body (natural or manmade objects) undergoes in its shapes, dimension and position in space and time domain.(變形指一個形變體【deformable body】(自然或人工物體)在空間和時間范圍【domain領(lǐng)域、范圍】在形狀、尺度和位置上經(jīng)受【undergo經(jīng)受、收到】的變化)【變形指一個形變體在空間和時間上經(jīng)受的形狀、尺度和位置的變化】Due to factors such as changes of ground water level, tidal phenomena, tectonic phenomena, etc, engineering structures (such as dams, bridges, high rise buildings, etc.) are subject to deformation.(由于【Due to】諸如地下水位變化、潮汐現(xiàn)象、地殼構(gòu)造【tectonic構(gòu)造的、地殼構(gòu)造的】現(xiàn)象等等的因素【factor】,工程建筑物(如大壩、橋梁、高層建筑等等)受到變形【deformation】影響【subject受……影響】)Deformation of engineering structures is often measured in order to ensure that the structure is exhibiting a safe deformation behavior.(工程建筑物的變形經(jīng)常觀測以保證建筑呈現(xiàn)【exhibit展現(xiàn)】安全變形行為)【工程建筑物的變形經(jīng)常觀測以保證建筑物的變形在安全范圍內(nèi)】Cost is more than offset by savings and by improvements in safety both during and after constructions.(As a result, the design, execution and analysis of such surveys are a matter of considerable practical importance.(作為結(jié)果,這種測量的設(shè)計、實施和分析是一件有著相當大【considerable相當大的】的實際【practical實際的】重要性【importance重要性】的事情
