【摘要】 高炉属于特种构筑物,其扩容本身产生的加、卸载特征和一般建筑物的增层改造工程不尽相同,而有其自身的特点。从高炉扩容工程的特点出发,对高炉扩容改造实现的途径、荷载的组成与变化特征及其对地基变形的影响进行了讨论。结合工程实例,提出了天然地基条件下地基基础评价的主要内容以及必须注意的主要岩土工程问题。更多还原

【Abstract】 As the special stucture,the reloading and unloading characteristic during the volume expansion of high stove is indescribable to the reconstruction of common building.Based on the characteristic of expansion engineering of high stove ,some problems such as the expansion approach,the loading state and it’s alterant characteristic,inchluding it’s impact on the settlement of the foundation soils has been discussed in detail.Considering some successful examples had been completed in the volume expansion of high stove,the primary geotechnical engineering problem which need to be noticed in foundation evaluation on natural subgrade has been mentioned.更多还原
