【摘要】 通过整理大量的岩土工程、工程地质与水文地质勘察资料,总结了黄河三角洲地区软土的特征。同时论述了与软土层相伴生的无粘性土的地震液化性质。提出了该地区的地基处理方法。黄河三角洲60%的面积范围内发育软土层,软土层由近饱和或饱和的粘性土、淤泥及淤泥质粉土组成,属冲积与滨海～浅海沉积。该三角洲地区地基处理宜采用换土垫层、挤密桩、化学加固、桩基、箱基与箱桩等方法。更多还原

【Abstract】 Characteristics of soft soil in the Yellow River Delta were summarized, by analyzing the data from geo-technique, engineering geology and hydrogeology investigation reports. Meanwhile liquefaction property of non-cohesive soil neighboring with soft layers was discussed. Some methods of foundation treatment for the delta are proposed in the paper. Soft soil layers are developed in the 60% area of the Yellow River Delta, belonging to alluvial deposit and shore-shallow sea deposit,which are made up of clayed soil,muck and mucky silt in a state of near-saturation or saturation. Cushion, compacted pile, chemical improvement, pile foundation, box foundation, box-pile foundation are suitable for ground treatment in the delta region.更多还原
