置换强夯和普通强夯交替加固地基在膨胀土中的应用

Application of Foundation Strengthened by Replacement Dynamic Compaction Alternated with Common One in Expansive Soil

通过项目实例阐述置换强夯和普通强夯交替加固在膨胀土中的应用,经交替处理后提高了复合地基承载力、消除差异沉降,达到了加固深度。指出强夯法与其它的施工工艺相比有较多优点,具有能级高、冲击力大、影响深度大、加固效果显著、适用范围广、方便快捷、工期短、施工费用低等特点,可广泛应用在工业厂房建设中。

The paper presents the application of strengthening of replacement dynamic compaction alternated with common one in expansive soil based on an example. For composite foundation treated with the compactions alternately, the bearing capacity is increased, differential settlement eliminated and strengthening depth reached. Compared with other construction process, dynamic compaction with such advantages as great impact, deep effect, effective strengthening, applicability, convenience, short duration and low cost can be widely used for industrial plan construction.
