一、浅层处理浅层处理方法主要有表层压实法、重锤夯实法、垫层处理、桩式处理和加筋处理等。表层压实法和重锤夯实法是通过机械碾压、机械振动或重锤夯击能量等对浅层的杂填土、黄土、松散粉质土、一般粘性土等压实或夯实,使裘层形成一层较均匀的,具有一定强度的“硬壳层”。垫土层处理是以砂或砂石、碎石、灰土、素土、煤渣等作为材料在原地基上加覆垫层或清挖部分软弱土层再加覆垫层。垫层具有一定的承载能力,能够有效地扩散上部荷载。桩式处理是采用短预制桩、楔形预制桩,夯扩碎石桩、灰土桩、布袋砂桩或布袋碎石桩等穿过浅层
First, the shallow treatment Shallow treatment methods are mainly surface compaction method, hammer ramming method, cushion treatment, pile processing and reinforcement treatment. Surface compaction and hammer ramming method is through mechanical rolling, mechanical vibration or hammer ramming energy on the shallow miscellaneous fill, loess, loose silty soil, clay and other general compaction or compaction, so that fur Layer to form a more uniform, with a certain intensity of “hard shell ”. Pad soil treatment is sand or gravel, crushed stone, lime soil, plain soil, cinder, etc. as the material in the original foundation plus cushion or clear some of the soft soil layer plus cushioning. Cushion has a certain bearing capacity, can effectively spread the upper load. Pile-type treatment is the use of short prefabricated piles, wedge-shaped precast piles, tamping gravel piles, lime soil piles, bagging piles or stone piles and other gravel pile through the shallow
