渭河电厂冷却塔高70米,水池深2.2米,直径60米,属地基浸水可能性大的水工构筑物。设计要求消除湿陷性,地耐力达15吨力/米~2。冷却塔地基处于渭河Ⅱ级阶地。表层为填土层(厚2.5～3米),一般较密实,但均匀性差,不宜作主要建筑物的天然地基。中层为黄土状轻亚粘土层(厚约4米),结构性差,压缩性高,属Ⅱ级非自重湿陷性黄土地基。在该层内还有一厚约1米的软弱夹层,其容许承载力为10吨力/米~2。下层为压缩性低、固结较好的亚
Luohe Power Plant cooling tower is 70 meters high, 2.2 meters deep and 60 meters in diameter. It is a hydraulic structure with high possibility of water immersion in the foundation. The design calls for the elimination of collapsibility and a ground endurance of 15 tons force/meter~2. The foundation of the cooling tower is on the Weihe II terrace. The surface layer is a filling layer (2.5 to 3 meters thick), which is generally denser but has poor uniformity and should not be used as the natural foundation of major buildings. The middle layer is a loess-like light sub-clay layer (about 4 meters thick) with poor structural properties and high compressibility. It is a Class II non-self-weight collapsible loess foundation. In this layer there is also a weak sandwich with a thickness of about 1 meter, which allows a bearing capacity of 10 tons force/meter~2. The lower layer is low compressibility and good consolidation
