摘要
含水率较高的复合饱和土路基因其承载力过低,往往难以满足工程稳定性需求。通过振冲碎石桩处理路基的加固效能及承载力提高的机理分析,决定采用振动碎石桩进行处理,可有效提高路基承载力、降低沉降量以及提高抗剪性能与排水效果,在某软基处治工程中得到应用,表明采用振冲碎石桩具有较好的不良地质的处治效果,尤其适用于非饱和土路基。
Moisture content high compound saturated soil roadbed its supporting capacity excessively is low, often with difficulty meets the project need. Through inspires flushes the mechanism analysis which the garrulous stone marker processing roadbed the reinforcement potency and the supporting capacity enhance, decided uses vi- brates the garrulous stone marker to carry on processing, enhances the roadbed support roadbed capacity effective- ly, reduces the subsidence quantity as well as enhances anti -cuts the performance and the draining water effect, obtains the application in some soft base punishment project, indicated uses inspires flushes the garrulous stone marker to have the good punishment effect.
