膨胀土有限变形防上拱的地基结构和地基结构的施工方法
摘要：
本发明公开了一种膨胀土有限变形防上拱的地基结构和地基结构的施工方法，所述地基结构包括柔性垫层、筏板和伸入地基土内的加固桩，所述柔性垫层设置在地基土的顶面上，所述筏板位于所述柔性垫层上方，且所述筏板同时与所述柔性垫层和所述加固桩连接。本发明实施例的地基结构不仅有效保证了承载和沉降控制效果，还避免了因地基土的膨胀导致路基结构产生上拱病害。
摘要（英）：

The invention discloses an expansive soil finite deformation anti-arching foundation structure and a construction method of the foundation structure. The foundation structure comprises a flexible cushion layer, a raft plate and a reinforcing pile extending into foundation soil, the flexible cushion layer is arranged on the top surface of the foundation soil, the raft plate is located above the flexible cushion layer, and the raft plate is simultaneously connected with the flexible cushion layer and the reinforcing pile. The foundation structure not only effectively ensures the bearing and settlement control effect, but also avoids the arching damage of a roadbed structure caused by the expansion of foundation soil.
