Dynamic compaction treatment method for karst landform foundation
The invention discloses a dynamic compaction treatment method for a karst landform foundation. The dynamic compaction treatment method comprises the steps of construction preparation, site leveling, measurement and position arrangement, karst cave treatment, dynamic compaction detection and the like. In the treatment of the karst landform foundation, the dynamic compaction treatment of corresponding energy levels is carried out on the karst caves with different roof thicknesses aiming at the foundation with large karst cave range and wide distribution, different shock waves and dynamic stresses are generated in foundation soil, the bearing capacity and the compression modulus of the foundation can be effectively improved, the dry weight is increased, the void ratio is reduced, the collapsibility and the expansibility are eliminated, vibration liquefaction is prevented, the uniformity and compactness of a soil layer are improved, differential settlement differences are reduced, during dynamic compaction, point-by-point compaction is changed into full compaction, so that the ascertained hidden karst caves can be treated, the unascertained shallow karst caves can be directly treated, and the method is a quick, economical, simple and effective foundation treatment method.
本发明公开了一种喀斯特地貌地基强夯处理方法，该方法包括施工准备→平整场地→测量布位→溶洞处理→强夯检测等步骤。本发明对喀斯特地貌的地基处理中，针对溶洞范围大，分布广的地基，通过对不同顶板厚度的溶洞，进行对应能级强夯处理，在地基土中产生不同的冲击波和动应力，能有效提高地基承载力、压缩模量，增加干重度，减少孔隙比，消除湿陷性，膨胀性，防止振动液化，提高土层的均匀性、密实性，减少不均匀沉降差异，强夯时，从逐点夯击到满夯，不但可处理已探明的隐患溶洞，对那些未探明的浅埋溶洞也起到直接处置的作用，是一种快速、经济、简单有效的地基处理方法。
