高速公路横向非对称路基开裂的实例分析

Analysis on Case of Transverse Unsymmetrical Expressway Roadbed Cracks

软土地基上的高速公路横向非对称路基,由于路基横断面方向上的不均匀沉降,易导致路基表面纵向开裂,严重影响路基边坡的稳定性。因此,设计中要综合考虑路基横断面方向上的地基处理方式,防止不均匀沉降的发生。

Transverse unsymmetrical roadbed constructed in soft ground is usually suffered from unequal settlement in subgrade cross-section and easy lead to the rapture on the surface of roadbed,which affects the stabilization of roadbed slope seriously. Therefore,the disposal manner of roadbed in subgrade cross-section should be considered comprehensively in study in order to prevent the happening of unequal settlement.
