In order to realize the reasonable design of the new-type pile-slab subgrade, this study relied on the reconstruction and expansion project of the G5011 Wuhe Expressway from Lintou to Longxi Interchange to construct a pile-slab subgrade model with 15 holes and 6m each. The displacement of the wet joint of the pile-slab subgrade was obtained through the full-scale model. Based on the separate modeling method, the load-displacement curve and the load-stress curve are in good agreement with the actual test results. Linear analysis. Combined with the full-scale component static performance test, it is verified that the wet joints of the constructed pile-slab subgrade are basically in the linear elastic working stage under the design load frequency combination condition, which can be applied to engineering.
