【摘要】 地基处理最终沉降量和理论计算值往往存在一定的差异,静载试验时桩头状态的改变会明显影响到沉降曲线,这就为人为地创造一种预定的更合理的沉降曲线提供了依据。褥垫层的设置使每根桩相互独立,桩、桩间土和基础变形不同步,削弱了结构整体抗震性能。而采用"桩伴侣"作为构造措施,桩顶预留沉降,使复合地基桩在高度范围内对地基土形成一定的约束,在提高竖向承载力的同时也提高了地基土的水平承载力。更多还原

【Abstract】 Foundation treatment of final settlement and theoretical calculation values tend to exist certain difference,static load test of pile head of state changes will greatly influence the settlement curve,that is to artificially create a predetermined,more reasonable settlement curves provide the basis for.The cushion is arranged to separate each pile,pile,the soil between the piles and foundation deformation is not synchronous,weaken the overall structural performance.Technical measures can still use "pile partner"as structural measures,the pile top settlement reservation,the composite foundation formed certain constraints on the foundation soil in the altitude range,to improve the vertical bearing capacity and improve the horizontal bearing capacity of foundation soil.更多还原
