地基土经强夯法加固后,其强度提高过程大致可分为四个阶段:夯击能量转化,同时伴随强制压缩或振密(表现为土体中水及气体排出,孔隙水压力上升化粪池模具 精密铸造 钢纤维 盐水注射机 风电基础模具 nsk轴承经销商 nsk轴承总代理 保定空调移机);土体液化或土体结构破坏(表现为土体强度降低或抗剪强度丧失);排水固结压密(表现为渗透性能改变,土体裂隙发展,土体强度提高);触变恢复并伴随固结压密(包括部分自由水又变成薄膜水,土的强度继续提高)。
After the foundation soil is strengthened by dynamic compaction, the
process of strength improvement can be roughly divided into four stages:
energy conversion of compaction, accompanied by forced compression or
vibration compaction (manifested as water and gas drainage, pore water
pressure rise); liquefaction of soil or structural damage of soil
(manifested as soil strength reduction or shear strength loss); drainage
consolidation compaction (manifested as permeability change, soil
cracks development). Thixotropic recovery is accompanied by
consolidation and compaction (including partial free water turning into
film water, and soil strength continues to increase).
