摘    要:在基坑监测实践中发现了基坑平面形状与基坑稳定性的内在联系,给出了椭圆形基坑、圆形基坑、矩形基坑的应力与位移监测数据,以实测数据为依据,指出了类圆形基坑的优越性,得出了类圆形基坑承载能力与坑壁稳定性优于矩形基坑的结论,利用三维有限差分理论分析了类圆形基坑和矩形基坑的承载能力与坑壁稳定性,介绍了基坑监测采用的方法和监测过程。

关 键 词:基坑  形状  稳定性  椭圆形基坑  圆形基坑  矩形基坑  原位监测

Abstract:The relationship between the plane shape of foundation pit and its stability is found in foundation pit observation practice.It furnishes observation data of stress and displacement of ellipse foundation pit,round foundation pit and rectangle foundation pit.The superiority of ellipse foundation pit and round foundation pit is pointed out,based on site observations.It reaches the conclusion that the ellipse or round foundation pit advantageous than the rectangle foundation pit.The load-bearing capacity and pit wall stability of ellipse or round or rectangle foundation pit are analyzed by three-dimensional finite difference integral method.The ways and process of foundation pit observation are given.
Keywords:foundation pit  form  stability  ellipse foundation pit  round foundation pit  rectangle foundation pit  site observations
