Open caisson type soft soil foundation and soft soil foundation reinforcing method
The invention discloses an open caisson type highway soft soil foundation reinforcing method and belongs to the technical field of geotechnical engineering and road engineering. The open caisson type soft soil foundation sequentially comprises a pavement structure layer (1), a foam light soil roadbed layer (2), a replacement structure layer (A) and a deep and thick soft foundation layer (B) from top to bottom. The soft soil foundation reinforcing method comprises the following steps that in a set range, an original soft soil foundation is excavated, and a deep and thick soft foundation layer (B) is exposed; and in the excavated original soft soil foundation area, a replacement structure layer (A), a foam light soil roadbed layer (2) and a pavement structure layer (1) are sequentially constructed above the deep soft foundation layer (B) from bottom to top, and the open caisson type soft soil foundation is obtained. According to the open caisson type soft soil foundation and the soft soil foundation reinforcing method, no extra additional stress is generated, differential settlement after construction is reduced, the overall strength of the roadbed is high, deformation after construction is small, the construction speed is high, the construction period is short, the flexibility is high, and the application range is wide.
本发明公开了一种沉井式公路软土地基加固方法，是用于岩土工程和道路工程技术领域。该沉井式软土地基自上至下依次包括路面结构层(1)、泡沫轻质土路基层(2)、换填结构层(A)，以及，深厚软基层(B)。该软土地基加固方法包括以下步骤：在设定的范围内，针对原始软土地基进行开挖，露出深厚软基层(B)；在挖除的原始软土地基区域，于所述深厚软基层(B)的上方自下至上依次构筑换填结构层(A)、泡沫轻质土路基层(2)，以及路面结构层(1)，得到沉井式软土地基。该沉井式软土地基及软土地基加固方法无额外的附加应力产生，减少施工后不均匀沉降，路基整体强度高，施工后变形小，施工速度快、工期短，并且，灵活度高、适用范围广。
