大连市北海头热电厂建在滨海人工堆积阶地上。表层杂填土、主要由炉渣、碎石、粘性土等组成,层厚约4m,上部中密、下部稍密,[R]=9tf/m~2。第二层淤泥质轻亚粘土,层厚约2m,黑色,呈流塑状,[R]=5tf/m~2。第三层碎石土,层厚约0.5m,稍密,[R]=18tf/m~2。第四层为强风化板岩,其上约2m厚为粉状,以下为碎块状。地下水位0.8～1.2m。地基软弱不能直接利用,按当地习惯,采用予制钢筋混凝土桩基础。桩基础投资大、造价高,需耗用大量的
The Beihaitou Thermal Power Plant in Dalian City is built on artificial terraces on the coast. Miscellaneous surface fill, mainly composed of slag, gravel, cohesive soil, layer thickness of about 4m, dense upper and lower part, [R] = 9tf/m~2. The second layer of silty light sub-clay, about 2m thick, black, was flow-shaped, [R] = 5tf/m~2. The third layer of gravel soil is about 0.5m thick and slightly dense, [R]=18tf/m~2. The fourth layer is strong weathered slate, about 2m thick on the slate, the following is lumpy. Groundwater level is 0.8 ~ 1.2m. Weak ground can not be used directly, according to local habits, using pre-made reinforced concrete pile foundation. Pile foundation investment, high cost, need to consume a lot of
