武麻高速公路三里桥互通软土地基工程地质特征及处治设计

Engineering Geological Characteristics and Treatment Design of Soft Ground in Sanliqiao Interchange of Wuhan-Macheng Freeway

阐述武麻高速公路三里桥互通软土地基工程地质特征,针对一般路段、涵洞通道和桥梁等三种工程位置容许工后沉降的不同要求和不同工点的软土工程地质条件,通过稳定性和沉降计算,设计确定了相应的软基处治措施,提出了沉降与稳定观测方法,指出了施工注意事项。

The engineering geological characteristics of soft ground in Sanliqiao interchange at Wuhan - Macheng freeway is described, on the basis of analyzing those allowable settlements after construction and geological conditions for common road, culverts, passages and bridges respectively, then combining with stability and settlement calculation, the authors design the corresponding treatments to tackle issues concerning soft ground, and propose the observation methods to survey the settlement and stability, meanwhile, the necessary notices in construction are pointed out.
