为提高基土的密实度和承载能力,通常采用的办法是夯击或碾压。对于处在最佳含水量上下的土壤,即现场表现为土体手握成团、落地即散的土壤是越夯越密实。对于含水量过大的土壤,即现场表现为手握土体能出水印、甚至粘手、土团落地不能散开的土壤却不能夯击, In order to increase the compactness and load-bearing capacity of the foundation soil, the commonly used method is slamming or rolling. For soils that are located above and below the optimum moisture content, the soil on the site is soiled by densely grounded soil that is held by the soil and scattered. For soils with excessive water content, the soil on the site is a soil that can hold a watermark on the soil, even sticky hands, and the soil cannot fall apart.
