| 摘 要： | 在软土地基上建设道面工程,采用排水固结法处理软土地基,是经济有效的地基加固方法之一。但在不同时期扩建的道面建筑物,在新老道面结合部位会出现不均匀沉降,导致道面工程病害,危及使用安全。通过软土地基排水固结加固处理的机理分析,结合机场道面工程的实例分析验证,提出经济有效且方便实用的预防治理措施。

| Abstract: | Drained consolidation method is an economical effective soil treatment for the construction of airport pavement on the soft foundation. For the extended airport pavement construction in different stage, differential settlement may occur in the combined part of the new and old surfaces, which result in pavement distress and endanger airfield operation safety. Through one pracdcal engineering example, This paper analysed the mechanism and engineering cost of drainage consolidation treatment tor soft foundation, which is verified effective and ecomomical. |
