摘　　要：东营地区地处黄河三角洲,其地层主要由第四纪新近沉积土和一般沉积土构成。其特点是地层较软弱,天然地基承载力低,承受荷载后地基变形较大。为了适应东营地区天然地基承载力低的特殊地质情况,目前常用的地基处理方法是水泥粉体喷射搅拌桩复合地基。采用水泥粉喷搅拌桩复合地基处理技术以后,复合地基承载力可提高到天然地基承载力的1.22.3倍。The Dongying area is located on the Yellow River delta, and the strata in the area are mainly composed of the quaternary recently deposited soil and commonly deposited soil. The stratum soil in the area is weak, the natural foundation bearing capacity is low, and the loaded foundation deformation is large. In order to overcome the shortcoming of natural foundation, the composite foundation with cement guniting and mixing piles is widely used to treat the natural foundation. Having been treated with coment guniting and mixing piles, the bearing capacity of composite foundation can be increased to 1.2 to 2. 3 times that of natural foundation.
