Adjusting method for pile-soil combined action of end-bearing rigid pile composite foundation
The invention discloses an adjusting method for pile-soil combined action of an end-bearing rigid pile composite foundation, which belongs to the technical field of foundation engineering, and is characterized in that the end-bearing rigid pile composite foundation comprises rigid piles, inter-pile soil, a mattress layer, an XPS extruded sheet and a foundation raft; a traditional mattress layer is reserved, the XPS extruded sheet is vertically embedded into the mattress layer, the two faces of the XPS extruded sheet are protected through the steel plates with the thickness being 1-2 mm, the situation that the extruded sheet is locally crushed in a point mode through broken stones in the mattress layer in the stress process is avoided, and meanwhile the rigidity of the XPS extruded sheet on the yield platform section can be improved to a certain degree through the steel plate hoop effect. The requirement for the large rigid pile top vertical load of a high-rise building can be met through the XPS extruded sheet with the small yield strength, the manufacturing cost is low, and construction is very easy.
本发明公开了一种端承刚性桩复合地基桩土共同作用的调节方法，属于地基基础工程技术领域，其技术方案要点是，包括刚性桩、桩间土、褥垫层、XPS挤塑板及基础筏板；保留传统褥垫层，将XPS挤塑板竖向嵌入褥垫层内，XPS挤塑板两面采用1～2mm厚的钢板进行保护，避免受力过程中褥垫层中的碎石对挤塑板进行点状局部压瘪，同时钢板套箍作用也能在一定程度上提高XPS挤塑板在屈服平台段的刚度。本发明可以通过较小屈服强度的XPS挤塑板来满足高层建筑较大的刚性桩顶竖向荷载要求，且造价较低，施工非常简单。
