为了进一步挖掘宝钢原料堆场地基的设计潜力,在原料堆场进行了大型砂桩地基堆土试验。在试验中埋设了测斜仪,以量测地基的侧向变形。从土力学的理论和实践可知,在垂直荷载作用下地基不仅产生垂直变形,还会产生侧向变形,尤以软粘土地基在大面积荷载下的情况更为显著,无论计算荷载面积本身的沉降或对邻近基础的影响都必须予以考虑。近年来由于大面积堆料而引起厂房或露天车间柱基础发生沉降、倾斜及位移,严重影响生产的事故在软粘土地区已屡见不鲜。如果设计时能全面地考虑堆料对厂房柱、墙以及基础和地基 In order to further explore the design potential of Baosteel’s raw material storage site, a large-scale sand pile foundation test was conducted in the raw material storage yard. An inclinometer was buried in the test to measure the lateral deformation of the foundation. From the theory and practice of soil mechanics, it is known that the vertical deformation not only causes vertical deformation, but also causes lateral deformation, especially when the soft clay foundation under large-area loads is more significant, regardless of the settlement of the calculated load area itself. Or the impact on the neighboring base must be considered. In recent years, due to large-area stacking, the settlement, tilt, and displacement of the foundation of the factory building or open-air shop have been caused. The accidents that seriously affect production have become commonplace in soft clay areas. If the design can be fully considered stacking material on the plant pillars, walls and foundations and foundations
