Title:
舗装道路の段差緩和構造及び段差緩和工法
Document Type and Number:
Japanese Patent JP7330073
Kind Code:
B2
Abstract:
To provide an unevenness alleviation structure and unevenness alleviation method for paved road that effectively alleviates unevenness and does not significantly hinder the passage of vehicles even when there are large steps on a road due to a large-scale earthquake and the like.SOLUTION: An unevenness alleviation structure is constructed by estimating an unevenness alleviation shape through the application of a nonlinear FEM analysis in consideration of a rigidity reduction rate based on an initial rigidity and a rigidity after reduction in order to alleviate an unevenness when an uneven subsidence causes unevenness near a boundary between a roadbed 120 or a base course 110 of a paved road and a structure 130. The unevenness alleviation structure includes a reinforcement mat 10 that is laminated and embedded in the vertical direction in advance in the roadbed 120 or the base course 110 directly above the boundary. The reinforcement mat 10 is formed by surrounding a filler 20 with a reinforcement material 30 with at least one laminated layer provided on one side in the length direction. A rigid member 40 having a rigidity higher than that of the filler 20 is arranged on the unevenness side predicted to occur near the boundary.SELECTED DRAWING: Figure 1
