公路路基采动稳定性计算

Evaluation on Stability of Mining Disturbed Highway Roadbed

在公路下进行地下采矿 ,因采动引起的地表移动和变形导致公路路基的稳定性受到影响。以某煤矿为例 ,提出了路基稳定性的计算公式 ,可用于评价地下采动公路的路基稳定程度。

When mining underground beneath highway, surface movement and deformation caused by mining disturbance will influence the stability of the highway roadbed. Taking a certain coal mine as example, a calculation formula has been proposed which can be used to evaluate the roadbed stability of highway disturbed by underground mining.
