气象因素对南京明城墙本体臌胀的影响分析

Analysis of the influence of meteorological factors on the wall expansion of Ming dynasty’s rampart in Nanjing

构筑物变形会对构筑物的安全造成严重的影响,会造成构筑物不均匀沉降、开裂及墙体剥落等危害。臌胀是造成构筑物开裂及墙体剥落的重要因素,对构筑物的危害是不可忽视的,但相对于其他墙体变形,其可控性更大。本文以南京明城墙为研究对象,基于实时监测数据及气象数据研究城墙本体臌胀变化规律及气象因素的影响,结果表明:气象因素对南京明城墙本体的臌胀具有一定的影响,其中降雨量和气温对明城墙本体臌胀具有明显的影响,而湿度对明城墙本体的臌胀影响不明显。研究气象因素对明城墙本体臌胀的影响,对于明城墙的管理与保护具有一定的参考价值。

Deformation of buildings has a serious impact on the safety of the buildings,causing uneven settlement,cracking and wall flaking.Expansion is an important factor causing cracking of buildings and spalling of walls,and the damage to buildings can not be neglected,and its controllability is greater than other deformation.Based on the real-time monitoring data and meteorological data,this paper studies the variation law of the wall expansion and the influence of meteorological factors on it.The results show that the meteorological factors have a certain impact on the expansion of Ming dynasty’s rampart in Nanjing,indicating that rainfall and temperature have a significant impact on the wall expansion of the Ming dynasty’s rampart,and the effect of humidity on the expansion of the wall of the Ming dynasty’s rampart is not obvious.Studying the influence of meteorological factors on the wall expansion of the Ming dynasty’s rampart has certain reference value for the management and protection of the Ming dynasty’s rampart.
