京沪高速公路改扩建软土路基处理技术及有限元分析
|
摘要
结合京沪高速公路改扩建工程,提出了浅层软基清淤换填、深层软基水泥搅拌桩复合地基和素混凝土桩复合地基为主的软基处理技术方案,并采用有限元方法计算分析改扩建软土路基的滑动稳定系数、工后沉降等,保障了改扩建工程软基处理技术的可靠性与合理性,为类似改扩建软基处理提出技术借鉴与经验。
According to Maozhan expressway expansion engineering, the treatment technology of expansion soft foundation were put forward including dredging and filling, cement mixing pile composite foundation, and plain concrete pile composite foundation. The sliding stability coefficient and post-construction settlement were calculated and analysed for reliability and rationality by finite element method. This achievement can provide technology reference and experience for similar expansion engineering.
