长春市粘性土建筑基坑悬臂桩支护设计计算方法探讨

长春市建筑基坑支护一层地下室采用多悬臂桩支护体系，结合长春市粘性土为超固结土的特征，选用静力平衡法、Blum法、极限平衡法、试算法等4种常用的悬臂桩支护设计计算方法进行探讨，并在计算时对相应的计算参数进行适当调整，通过对比分析得出极限平衡法及其相应的参数值适合于长春市粘性土的悬壁桩支护设计计算。

Research on the Numerical Procedures of the Cantilever Piles' Design of Supporting While Used in the Architectural Foundation Dell of Changchun's Cohesive Soil

Supporting technique of cantilever piles are wide-ranging supplied to supporting of foundation dell of one-store basement in Changhchun City.In view of existing situation, the paper combines with the cohesive soil's properties of the city use four main numerical procedures of the cantilever pile's of supporting design, namely static balance method, blum method, limiting equality method, trial and error method. By means of comparison and analysis, limiting equality technique and corresponding parametric value are more suitable for use to the special technique of design of cantilever piles in Changchun City.
