素混凝土桩复合地基在西安地基处理工程中的应用

The Application of Pure-Concrete-Pile Composite Subgrade in Ground Treatment at Xi'an

针对建筑物对地基承载力和变形的要求和地层性状,结合素混凝土桩复合地基的特点,采用素混凝土桩复合地基进行地基处理,并对复合地基参数进行了设计。通过试桩试验和工程桩的检测,表明素混凝土桩复合地基对地基承载力提高幅度大,减少地基变形明显,很好地满足了建筑物对地基承载力和变形的要求。

Considering the requirement of buidings for subgrade bearing capacity and subgrade deformation and the characteristics of stratum and Pure - concrete - pile composite subgrade , Pure - concrete - pile composite subgrade is applied to ground treatment. Measurements of the using of Pure - concrete - pile and the choosing of parameter are also discribed. Throuth examination and checking,it has been proved that Pure - concrete - pile composite subgrade can improve subgrade bearing capacity and decrease subgrade deformation,and that it can fully satisfy the needings of subgrade bearing capacity and subrgade conformation of buidings.
