高速公路路基开裂处理的实例分析

Example Analysis on the Treatment for Expressway Subgrade Cracking

针对一运营中的高速公路路基开裂的情况,分析了开裂产生的原因,得出了填料不均、压实度不足及水的影响是路基开裂的重要原因,应采取应急措施进行处理。提出了采用"钢板桩加强夯对路基进行处理,同时加强排水措施"的治理方案,在保证路基稳定的情况下,对路基进行加固处理,同时应加强路基排水等辅助设施进行综合治理等结论。

Based on the subgrade cracking situation of an expressway in operation, it is found by analyzing that the main reasons that lead to cracking are non- uniform placement, insufficient degree of compaction and the influence of water which require emergent handling. A treatment scheme of ＂ use steel sheet piles and dynamic compaction to deal with the subgrade and at the same time strengthen drainage measures＂ is proposed to consolidate subgrade when it ＂s stable and meanwhile improve drainage and other supporting facilities to treat cracking comprehensively.
